Here's A foolproof way to get my attention on a packed Saturday night at my bar, Coyote Ugly in Oklahoma City: Flash a $100 bill and yell “Keep the change!” I promise it will make you my number one priority the rest of the night. THAT SAID, I’ll still respect you if you tip at least a dollar a drink. BAD PICKUP lines are an occupational hazard. The worst one I’ve heard? “Is that a keg in your pants? Because I’d sure like to tap it.” YOU KNOW a bartender is legitimately into you if she keeps talking to you after you’ve paid the tab. All that talk before you get the check? It’s flirting in the name of the best possible tip.
