Paris, about 12 years ago, in a side street off the Rue Saint-Denis. I walked around for ages and eventually settled on a plump, mature lady with gargantuan tits (there wasn't much else available that night). She led me inside the building and up about 4 flights of stairs, passing a security guy on one of the landings. Once we were inside her room and I'd handed over the folding she stood in front of the door and started haranguing me in French, the gist of it being that if I didn't hand over more money then she'd scream and call in security and say I'd attacked her. I stood my ground and kept on repeating politely but firmly to GCSE standard that I'd already paid her, had done nothing wrong, and wanted to leave. This to and fro seemed to go on for an age but was probably only a few minutes. She did actually call in the security guy, who was quite young and clean cut and declined to do or say anything to assist her. After he ducked out she let me go. Ludicrously, as I made to leave she thoughtfully reminded me that I was about to leave my umbrella behind! I think I lost 50 or 70 francs or euros, although to be honest the whole episode was more entertaining than sex with her would have been. Never punted before or since in France. With hindsight I reckon I had a lucky escape.
