MANY years ago I went to a spa place in Loughton.
It was £15 for entry and a massage as I recall, which I paid using 2×£10 notes and the receptionist gave me change.
My masseuse was very skinny (not my type) with small boobs (ditto) and not really terribly friendly.
But i was naked on a table and horny, so went ahead - the massage was rubbish, but nevertheless she got my little fella standing to attention and then asked for £15 extra for a HJ.
By now I wasnt really feeling like I was too bothered either way, and said that I only had a tenner so if that was OK with her I would have the hj but if not just finish the massage please.
She took the £10 note I proffered and did the business.
10 mins later I was in the shower when the curtain was pulled back and a now very aggressive masseuse screamed at me that the receptionist had given me a £5 note in change, and SHE WANTED IT as I obviously had more than just £10 on me.
She was waiting at the exit when I was leaving and I gave it to her, as my - "but we agreed £10" fell on deaf ears and I feared a stabbing or something.
I did actually need most of that £5 for fares home which was why I had Claimed to only have £10.
Anyway - lesson learned
