Referring a customer to a competitor will likely result in:

The most appropriate outcome of referring a customer to a competitor is that it can indeed create a positive impression of your business, which may lead the customer to seek you out for future needs. When you prioritize the customer's best interests by directing them to another business that better meets their requirements, it demonstrates integrity and a commitment to customer satisfaction. This behavior can build trust and loyalty, as customers appreciate transparency and feel valued when the focus is on their needs rather than purely on making a sale.

On the other hand, there are reasons that the other outcomes are less likely. While it is possible that a customer might choose not to return to your store after being referred to a competitor, it is also reasonable to believe that they will remember your helpfulness and feel inclined to return for future inquiries, especially if they perceive you as a reliable source of guidance. Additionally, while referring a customer to a competitor may seem like a lost sales opportunity in the moment, it can actually turn into a positive marketing strategy, as satisfied customers often share their experiences, potentially bringing in new business.
