Where in the hell are all these bars that give you free drinks for tipping well? I always tip bartenders and servers (worked in a bar in college) and except for the bar I used to work at I've never received a free drink at a bar in my whole life.

I do have one exception to the always tipping the bartender rule. If I'm having to wait half an hour for my drink because the bartender thinks he is the offspring of Meadowlark Lemon and Tom Cruise's character in Cocktail and I'm dying of thirst because he is too busy juggling thirty seven different bottles of rum then he gets no tip.
