The American mentality is to look like a good tipper. I have a well off Jewish friend who tips 10% only and that's her. She told me you don't tip on take out unless they deliver, but then tips are expected but not compulsory. People do go out when they are short on funds for an occasion because it's called being social. I know when friends are short on funds a fixed price buffet is often a good idea or a fixed price menu is decided beforehand and some better off friends help make up the difference in the service charge. People should not feel as if they cannot go out ever because of funds and to fear the tips. I do feel the American mentality is flawed, because I know the server doesn't really care and just wants tips, so if they fake it, why should I fake it and give them a good tip for bringing me a beer? It's a faux game, but a server that goes out of their way to help will get a good tip. Personally I don't care if I look like a 'bad' customer because I didn't tip generously, why should you? If they give you bad service after that because of it, it shows what a poor place it was any how.
