Talk to any waiter or waitress. They will tell you which ethnic group is the worst tippers.
My daughter worked her way through college as a waitress. You already know the answer to that question.
As a result of her experience, I usually tip 20%-25% for good service, less if adequate.
Bad service? 15%, and the establishment never sees me again (though I'll give 'em a second chance to redeem themselves). However, I can't recall the last place like that, as I don't go out that much and there are only a few places I frequent.

Yeah, even members of that same ‘ethnic group’ will tell you which ‘ethnic group’ are the worse tippers.
