I do wonder whether the original message is (as some have jokingly suggested) a coded message that watersports are £10 extra. But, while I'm no expert on golden showers, that does sound awfully cheap. That apart, I would have thought anybody providing sexual services would have a vested interest in seeing that their clients are nice and clean. So to provide a £10 disincentive seems just nuts (Is a clean towel £5 on top of that, I wonder.) Perhaps, as one poster has suggested, she gets off on male body odour. But I doubt it. I just don't think she's thought through the implications. (Unless she is a former Ryanair stewardess, and if you don't have the "optional" shower, you can only have a handjob: in which case the shower towel WILL be an extra fiver!)
