Another line used on me (which I quite liked), whilst on a gig, was when an attractive woman came up to me (who'd been smiling and eye-balling me all night), and while I was tearing down, asked point blank "Do you want to have breakfast?"
I went over to the band leader (an empathetic soul bless his heart) and said "Listen, I have a situation here that I have to act on immediately while she's still in impulse mode. Can you and the other guys schlepp my stuff to the truck and load it, so I can split now?" He winked, smiled and said "Go for it."
I confess I'm a total sucker for attractive women with good lines...both verbal and spacial. (grin)
