I remember hearing about a group of restaurants making a fortune from selling cheap liquors with forged high dollar labels. They made a fortune, and would only rarely have a customer that actually could tell the difference. When they got a complaint, they would just trot a bottle of the real stuff out. It was amazing how long they got away with it. In a way, it goes to show how few people can recognize the subtle difference between a great product and a good one. It often boils down to the amount of experience with the type of product, and a lot with the ability of the person. We all like to go out to a great restaurant, but few have to taste buds to distinguish the subtle flavor differences between a very good chef and a great chef. It does not mean we cannot enjoy a great meal, just that there are people who cannot enjoy a lesser meal, once they have experienced the best.
