Early in my mongering career, I turned down FS from an (apparent) FS provider. It was the first time a girl had offered me FS. First she asked if I "liked what I saw" and when I said yes, then asked if I wanted "sexo". It freaked me out a little. I was still pretty new to the hobby and just wasn't prepared for it. Anyway, she cut the session short. Really short. Like less than 30 minutes when I paid for an hour. I didn't tip her much, but it was clear she was pissed off and wanted me out of there. I never went back to that place and it ended up closing in less than year.
