TY - JOUR AB - Purpose The purpose of this paper is to examine the threshold effect of group size on customer's complaining intention under group service failures.Design/methodology/approach Based on two main laboratory experiments, through two 10Ɨ2 scenario simulation experiments, the authors examine the role of group size in customer's complaining intention.Findings Results show that: (1) the relationship between group size and customer's complaining intention follows an inverted ā€œUā€ type trend; (2) evaluation apprehension mediates the relationship between group size and customer's complaining intention; (3) relational distance can change threshold values and (4) relational distance moderates the relationship between group size and customer's complaining intention.Practical implications Managers should judge the threshold of group size through experience so as to have a preliminary understanding of customer evaluation concerns and complaint intention. In the face of service failure groups smaller than the threshold range, managers should divided the group into several small groups. For service failure groups larger than the threshold range, the opinion leaders in the group should be given more attention, so as to control the whole group.Social implications This paper is helpful to deeply understand the key role of group size in the process of customer complaints, and also provides decision-making basis for service enterprises to deal with group customer complaints.Originality/value There has been little research about the threshold effect of group size on customer's complaining intention. The previous studies on customer's complaining intention focus on its influences on group size, and draw a single common conclusion that the customer's intention to complain will increase with the growing number of groups increases. However, few studies are explored on the threshold of group size. Therefore, this paper will focus on the threshold effect of group size on customer's complaining intention to fill the gap.
