From our collective retail experience (and the retail experiences of many, many, many of the people we know), we started talking about what kinds of customers are our favorite kinds of customers. And there seems to be some common threads in our realms of experience. We talked about customers who are always nice and never yell, and customers who remember our names even when we aren't wearing company shirts and name tags, customers who talk to us about more than the weather and customers whose products or services we believe in. And then we came around to customers whose stores we like to shop in. And this brought up an interesting point. What kind of correlation is there between a customer whose store we enjoy and our enjoyment of that customer when he or she is in our store?
