We usually just tip the suggested amount. We are a family of 5 and we have a tight budget. I have been told on these boards that it is fine to tip only the suggested amount. We don't ask for any special treatment or extras. Last year we did give our waiter an extra $10 because he served us our own wine (from home) and never charged us the uncorking fee. We felt this warranted a little payback as he saved us more than that . Enjoy!
