"are you on Dave's Facebook?"
So, I was in a posh London winebar. I happened to have a plate of chips in my possession and when I stood up to offer them around the (fit) birds flocked to me. The 'Aircraft Simulation' line worked like a charm and the evening flowed on well. But did I get her number? For some reason "are you on Dave's Facebook?" was the best I could muster. At least she is, I guess.
