Across a series of lab and field studies, with a total sample of over 1200 participants, we investigate how the physical proximity between salespeople and customers can impact store loyalty, purchase intentions, and actual spending. An initial survey among a representative sample of retail salespeople reveals that they associate close physical proximity between employees and customers with positive consumer outcomes, an intuition that dovetails with prior research documenting the positive influence of such proximity on purchase intentions, particularly in nonexpressive consumption contexts. Contrary to this work, we demonstrate, across four studies in which proximity was both measured and manipulated, that store loyalty, purchase intentions, and actual spending behavior are negatively impacted when consumers encounter a salesperson who is standing close by (vs. farther away), particularly in expressive consumption contexts. Psychological discomfort mediates this effect, such that consumers experience greater discomfort when a salesperson is standing close by, which in turn decreases spending. Importantly, this phenomenon is moderated by identity relevance, such that the negative influence of salesperson-customer proximity specifically emerges when consumers think about products in terms of their ability to express their identities. These findings carry important implications for retailers operating in expressive consumption contexts.
