I used to work in a small little burger joint that specialized in great service. If you were a customer, you could barley tell who your server was because there was some much server interaction. One waitress would get your drink order, and another waiter would take your food order, another would drop your food. Someone else would swing by and check up on you and someone totally different would drop a check and your server would complete your transaction. It was fantastic service for the customer because everyone was paying attention to you but for some reason some people would still tip poorly because they did not feel like their waitress deserved to be tipped properly because she was never around. In my opinion this is the dumbest thing I have ever heard of. Unfortunately many people are actively looking for a reason not to tip or to leave a lot smaller tip regardless of whether or not they were taken care of. You would think this kind of a system would be highly enjoyed by the customer.
