Also, if I'm sitting at my table, and a dancer I'm not interested in sits down, how do I tell her I'm not interested without her getting angry. I've tried the "I'm not getting dances tonight" line, but it never seems to work.

It really depends on the girl. Normally I won't sit for more than a song or two without asking, and if they say they're not ready/they're not getting dances/they need another drink/etc., I tell them I've gotta get back to work, will check in on them later, and off I go.

If you're waiting on a certain girl, just say so. If it's a dancer that hasn't asked for a dance/you're not really 'feeling' her and she has just been sitting there for a while, the 'I need to run to the restroom/run outside to use my phone/go tip that random girl on stage' excuses are a non-dickish way to (hopefully) get her to move along.

You've got a question? Maybe I've got an answer..
