She was a DJ at a club we went to quite often, and when she agreed to go for a drink with me I was over the moon. She arranged for us to meet near the club the night after (a Saturday) and so I bought a new shirt, wore new cologne, had a wash etc, and was really looking forward to it. When I got there, however, and found her clutching a stack of flyers and nodding at me, I realised she had other ideas.
The next two hours were spent traipsing about the pubs and clubs of the town and handing out those bloody flyers to everyone we came across. She hardly spoke to me and by about half 11 I was furious and ready to go home. Then in a slightly deranged manner, she grabbed my hand and pulled me into the girls toilets of the pub for some dry-humping in one of the cubicles. Needless to say, I wasn't in to it one bit - and neither was she. I think she considered it a form of payment for the fact I'd just worked for her, for 2 hours, for free! I only ever saw her again at the club, but never spoke to her - so mortified was I about what had happened.
