I like tipping high on servers and bartenders who have been exceptionally nice to me. If someone is just friendly and helpful way beyond the call of duty, I'll probably drop a 25% tip in their lap just because if somebody makes my day, I want to make their day in return. And then there was when my favorite bartender left his job at my favorite bar... I think I tipped almost 50% on his last night as a parting gift.
