I have worked customer service in some capacity for almost 20 years. Being on the other end means I get to see the other side of the coin. It also means that I know how to treat someone serving me. I fully believe that if a customer is not rude, offensive or in some othe way coming across really wrong, the employee of the store/restaurant/ should only be thinking of one thing.....I represent this business to this customer. If I want them to come back I had better act like it. The owner of the place should also be looking for this.
