Prostitute? Me?

I was walking up the stairs from the bridge where two men were sitting, they had a few bottles in front of them and seemed to be drinking. When I were a couple meters from them one said "ooh here comes one [something or other].

They mumbled a little between them, said something I couldn't hear, and as I walked past the other said "how much do you want for an hour?"

I'm not sure if I should be flattered or offended, so I decided to go with the first.

Still, I can't help but feel it's a little like mistaking Winnie the Pooh for Bamse, the world's strongest bear...
