Probably the most bizarre hobby encounter I've had was almost 20 years ago in Prague, Czech Republic.
I'm in a subway station at an ATM at around 10pm and it's deserted except for this lady who's standing way too close to me and eyeballing me strangely. I'm a savvy traveler and assume she may be trying to spy how much cash I withdraw for a pickpocket setup so I take the usual precautions, cash in multiple pockets, palm the card and put it in a different one, etc...
Turns out she propositioned me for some pay for play as I'm walking away. I'm staying with some friends in a hotel off Wencelas Square and I'm telling her no I'm not interested as she follows me onto the street still talking to me quoting very very low prices. No one is following us so I'm no longer worried about a theft. She's not attractive, never has been, and is years past her prime, but I'm young dumb and full of cum so what the hell I'm all about doing things for the novelty of the experience.
We agree on 10 dollars for a BJ and so very shortly I find myself in a not quite dark corner on the streets of Prague within sight of Wenceslas Square getting head. She finishes me off, spits on the ground, and walks away without a word. I walk back to my hotel with a smile on my face and a good story
