A number of years ago my wife and I went to taco bell. We were the only people at the counter and we stood there for a good two or three minutes before anybody even came up to help us. They knew we were there because they were all standing in the back looking at us. The cashier finally came up when some more people walked in the door. She didn't even say, "Can I help you?" or anything. Just looked at us. My wife and I looked at each other and walked out the door without a word. Didn't go back to that particular one for a very long time.

Another time we went to Perkins. The waitress came up and asked us if we were ready at least a half a dozen times in less than two minutes. Didn't get us refills either. Needless to say she didn't get a very good tip.
