My first job when I went to Germany was working in a skin clinic. The local prostitutes arrived there on two days a week for their mandatory monthly check-up. There were several hundred in total and I got to know many of them to see, as they'd sometimes come with friends though it wasn't their turn. Some of them were the most beautiful women I'd ever seen.

Over the following few years I recognized several of them in trendy parts of the city, or at rock concerts or in discos, usually in the company of well-heeled men, and I'm pretty sure most of the men didn't know their background.
