Thanks guys. It was genuinely the first time I was put in that situation. I had requested my money back 3 times previously, twice it was handed back with no argument as they had lied about their services. The third was a Chinese girl in Bayswater. She was taking the piss, no FK, only mish, no second round even though I had confirmed all with the maid before the punt. Had a massive argument when she said there was no second round and asked for half my money back. Another prossie got involved and said I could see her instead for the remainder of the time but I was too pissed off to stay. Eventually another maid came, they phoned the original maid to confirm the services, the girl was shouting in her language but they did eventually give me half my money back.
In this instance I assessed the situation. They were genuinely scared of their neighbours finding out what goes on in the flat. They wouldn't risk the police being called in and I was firm that if I was touched I would be calling them. They didn't look like the type who would fight anyway, just scum who think it's an easy way to make money by scamming clients.
LL, i'm single and I was due to play football a little later anyway so any black eye could have been passed off as a elbow in the face accident.
