I actually find the way that tipping is so expected in America to be quite rude to be totally honest.

When I visited, my friends were always like "You must leave a tip, its how they do things here," and I would simply reply "If they deserve a tip, then I'll tip what I think they deserve."

One diner in LA actually put the tip charge on the bill! Safe to say, they didn't get one.
