Ignoring the red-neck wet dreams above, I differ only on one issue with Arsenal. My first offs were in 1995 and were guided by the excellent Gay Guide I bought in Foyles for a few pounds. The writer (his name was Michael (I think) Notcutt, advised us not to discuss payment before the deed. I never have, though if a guy asks me , I always tell him honestly. Only rarely has this happened. I always give the going rate, well-known to all of us and to the guys themselves, and then add a couple of hundred plus for taxi/ dinner.
The advice to give a small tip if you return to his bar is particularly apposite. The other guys will know that you offed him and ignoring him will result in his losing face.
Arsenal is right to emphasise the importance of respect. Not only is it right it improves performance....for both parties.. Enlightened self-interest, if you will.
