Most hospitality services are delivered in the same location in which they are produced, and, thus, their delivery involves the presence of other customers. Yet, the role of other customers’ physical appearances in influencing service encounter evaluations has received scant attention. Moreover, previous research shows that consumers with a low sense of power are motivated to seek status by engaging in conspicuous consumption. The current study examines the joint impact of other customers’ dress styles and the observer’s sense of power in influencing customers’ approach behaviors (e.g., willingness to stay longer in a restaurant, interact with other customers). The results from our experiment show that customers’ approach behaviors among observers with a low sense of power were significantly higher when other customers’ dress styles were formal rather than informal. Conversely, the effect of other customers’ dress styles was minimal among observers with a high sense of power. Results from this study indicate that approach behaviors mediate the impact of other customers’ dress styles on word-of-mouth intentions among customers with a low sense of power. The findings of this study help hospitality operators use dress codes to their advantage.
