D'oh!! Of all the details to forget, eh bobsy?
Tell your friend the ones that were staring and dribbling when she was doing her main routine are the ones to go after. Just go up to them and say "I think you liked what you saw." If they respond in the affirmative but she still isn't sure, add "Well, let me know if you want a dance" and go to leave him. Some will probably perk up and say "actually now that you mention it..." If on the other hand they react like a hungry dog that's having sausages dangled in front of their face, just ask "Would you like dance?" because there's no need for coy at this stage.
That could all be bollocks, of course. I've never studied the behaviour of strippers or their clientele, or interacted with them. Not once. No siree Bob(s).
