I'd do it for only one pint.
Reminds me of a punt (pre my time on UKP) when I turned up for a punt and the girl tried to sell me a duo with her very unattractive friend. I said no. She said can she stay in the room anyway? This was in a hotel so she'd have had to go outside I suppose. Anyway, I said she could stay. She the unattractive one couldn't keep her hands off me during the punt even though I pretty much ignored her. It was all a bit strange but quite a turn on at the same time. I doubt if it would have been as much fun if I'd paid her-then I'd have had to shag her!
