Not at my place of work but I had a mate who managed a souvenirs shop next to the Tower of London, selling rubbish souvenirs to the gullible. One night, at closing time, he locked up the shop and we had a good wank together between two of the racks of shelves. When he came he picked up a woolly hat off the display and wiped his cock on it. I presume that he threw it away afterwards - I least I hope that he did! It was very horny knowing that tourists were walking past the window a few feet away.
