Robots in service experiences: negotiating food tourism in pandemic futures

Purpose – This research discusses the role of service robots in gastronomic and dining experiences in a post–coronavirus disease (COVID) world. Design/methodology/approach – The research note draws on secondary data to analyse the use of robots as an important mechanism to address the impacts of global disease outbreaks on the food industry, as related to hospitality and tourism. Findings – Hospitality and tourism services are highly affected by the current travel bans, lockdowns and health-related rules that have emerged to manage the current pandemic (COVID-19). This research showcases the role of service robots in food encounters in hospitality and tourism as agents that contribute to safe and innovative experiences. Originality/value – This research note explores how the use of robots in tourism futures will not only transform food experiences, but it is also critical to sustainable development of communities and destinations in a future that will continuously have to deal with disease outbreaks and pandemics with continued travel mobilities.

The current coronavirus disease  pandemic raises new questions about this alliance between robotics and hospitality as a technological solution for the foodservice industry and food tourism experiences (Hong Zhu and Ping Chang, 2020;Lee et al., 2018;Seyitoglu and Ivanov, 2020a;Zemke et al., 2020), especially in a future where global disease outbreaks and pandemics are anticipated to be among the "new normal" (Jamal and Budke, 2020) along with, and possibly exacerbated by, climate change (Dogru et al., 2019;Semenza and Ebi, 2019). This research note draws on the published research literature and news media to discuss the opportunities and challenges presented by the use of robots as an important mechanism to address the impacts of pandemics on the hospitality and tourism industry.

Service robots in pandemic times and food tourism futures
Food services as part of the tourism system are vulnerable to natural hazards such as pandemics (Dube et al., 2020). The hospitality industry is one of the largest affected sectors (see, for example, Gö ssling et al., 2021) and measures to ensure food safety, the safety of visitors and service providers, and control risk perceptions are crucial (Handley, 2020). The implementation of robots in the face of global disease outbreaks must be effective to match individual and social needs (Lafranca, 2020). Robots can provide a 24/7 service (Park, 2020), and their design is vital to the effective adoption of service robots by gastronomic and dining experiences (Hong Zhu and Ping Chang, 2020). In this sense, according to Seyitoglu and Ivanov (2020a), appearance and functionalities emerge as significant attributes when planning a robotic experience. For example, "a humanoid robot can be used as a host inviting and entertaining guests in the restaurants, while a non-humanoid robot could be used to deliver the food" (p. 11).
Previous studies have underlined that demographic changes and patterns emerge as the biggest drivers of service automation in tourism . Nonetheless, the global outbreak has changed this scenario: now COVID-19 has taken over as the most important driver of automation (Zeng et al., 2020) and contact-free technologies including robotization to limit virus spread by front-line service providers are and will be of critical importance Seyito glu and Ivanov, 2020b, c). The pandemic has boosted robots to manage actual and perceived risk in the labour-intensive hospitality industry (Berreby, 2020). These include visitor concerns about food contamination, infection transmission during service provision and the potential lack of personal protective equipment to safeguard the health of frontline service providers.
Progress in the development of service robots, and the potential of their increased use as frontline providers to reduce human-to-human contact, has significant implications for gastronomic and food services, as observed in Figure 1. COVID-19 is speeding up the use of robots (Thomas, 2020) for food safety and as an avenue to provide biosecurity to tourism stakeholders . Automation technologies will be increasingly important for competitive advantage in hospitality and (food) tourism (Fusté -Forné and Hussain, 2021; Kuo et al., 2017). In particular, their use in enabling safe experiences is a prerequisite to rebuild tourism and proactively prepare for future disease outbreaks and pandemics that will continue to affect domestic and international tourism futures . This raises important questions for research and practice. What are visitors' experiences of robots in tourism and how are visitors perceiving robots in the food experiences in the context of the hospitality and tourism industry?
While previous studies (see  revealed that customers find robots in a restaurant context more suitable in roles such as cleaning, providing information or taking orders, robots are also adopted to cook and serve food . Practical examples demonstrate that robotization can foster not just competitive advantage but also personalization in food tourism experiences (De Kervenoael et al., 2020;Tuomi et al., 2020). According to Fusté -Forné and Jamal (2021), "roles in service robotics range from automation for novelty, for example, a restaurant that places a personal robot assistant on every table as a way to create a unique experience, to automation for improving service quality, such as in delivering orders efficiently and punctually" (p. 45).
Several examples show the kinds of robot-delivered experiences emerging in restaurants, with a primary goal to serve up safety (Lang, 2021). A simple change refers to the overall implementation of digital menus and Quick Response (QR) codes which represent a safe alternative to view menus and order (Littman, 2021). As automation and technology lead the restart of culinary experiences amidst a global pandemic, more and more service robots are adopted for delivering gastronomic and dining experiences, for example, as robot waiters (Hontoria, 2020). In Maastricht, a restaurant hired humanoid robots to greet customers, scan body temperatures or serve drinks to reduce person-to-person contact (Brady, 2020). Robotic food delivery is rapidly implemented by Food and Beverage (F&B) outlets as well (Albrecht, 2021), including meal delivery robots in airport restaurants (Baskas, 2021). A growing sophistication is especially observed in the rise of a robot that can cook (Wiggers, 2020) which will also drive gastronomic robotization in tourism futures.

Figure 1 Robots as providers in service experiences in food tourism crisis management
The current pandemic has severely impacted tourism, and the industry is scrambling to embrace new directions and innovations to recover and reassure travellers of safe and enjoyable experiences at their destination (UNWTO, 2020). From an academic perspective, Choi et al. (2021) explored how service robots deliver engaging customer experiences. Within the context of tourism, they reveal the influence of cultural background on how service experience provided by robots is perceived. Furthermore, Berezina et al. (2019) state that service automation in restaurants positively impacts visitor satisfaction. Service robots must not only provide safety in gastronomic and dining experiences but also trust (see, for example, Seyito glu and Ivanov, 2020b;Tussyadiah et al., 2020) which, together with the speedy advancement of technology, will also lead to increased robotization of food and gastronomic experiences in the future.

Conclusion
While hospitality has always been a "high-touch" industry, it has moved to "high-tech" dominant servicescapes (Benckendorff et al., 2005) and a rapid robotization of experiences (Zeng et al., 2020) due to the impact of the COVID-19 pandemic on tourism systems. The COVID-19 pandemic has shocked communities and destinations worldwide and put global threats to sustainable tourism futures. Global tourism faces an unprecented crisis which urges academics and practitioners to rethink many aspects of the industry, for example, host-guest encounters and service experiences. This research note has analysed service robots as a strategy to respond to global crises and to foster proactive responses in the hospitality and tourism industry. In particular, this research has discussed some of the challenges and opportunities facing food experiences in hospitality and tourism. Moving forward into (post-)pandemic futures involves rethinking travel and tourism for sustainability and resilience (Prayag, 2020;Nepal, 2020;Sigala, 2020), and an important aspect of this is service encounters and service provision. How will automation affect service-level jobs such as frontline hospitality providers? How will robotization affect the visitor experience? How will it affect food tourism and slow food practices that strive towards sustainability, safety and slow encounters between local producers, service providers and visitors? (see for example Fusté-Forné and Jamal, 2020).
Besides, how the service encounter notion of "hospitality" will be negotiated within this new robotic environment will be a crucial priority for future research and practice (Bowen and Morosan, 2018). Recent publications also indicate that service automation may lead to an anti-hospitality context derived from the implementation of robotics in economy-centred tourism development (Korstanje, 2020). The use of robots in tourism futures will transform (food) tourism experiences (Manthiou et al., 2020) and the huge impact of automation on the development of humanity requires that responsible robotics (Dignum, 2019;Van Wynsberghe and Sharkey, 2020) be put at the centre of the robotisation of tourism experiences. Developing ethical robotics arises as an important consideration for future research and practice (Bartneck et al., 2021;Fusté -Forné and Jamal, 2021). Responsibility is crucial in human-robot interactions and various researchers argue that service robots in service encounters must increase rapport building (Qiu et al., 2020) and improve on "human" technological skills (Tuomi et al., 2020). Further research needs to analyse the human dimension both from supply and demand perspectives as a crucial avenue to understand visitors' experiences of robots.
Also, recent research reveals that the development of automation and robotics in the hospitality and tourism industry needs to be scrutinised from an ethical and equity perspective (Gretzel et al., 2020;Jamal, 2019). Specifically, Mü ller (2020) argues that privacy or opacity should be further examined. By this Mü ller means that the complex and dynamic nature of robotics is urging a debate on the ethical issues derived from the planning and implementation of digital technologies in human-centred environments. Service providers in hospitality and tourism must not forget what "hospitality" means. While pandemic times threaten human-to-human contact in service encounters, robotics can and will continue to contribute to increase safety for service providers and visitors. But many questions arise as to what this means for hospitality and what are generally perceived to be co-created and co-consumed experiences. A critical priority in future research and practice also is to understand what constitutes fair and ethical human-robot interactions in service delivery and visitor experience in the hospitality and tourism context.
