Lol. I had this happen to me. A very attractive girl approached and propositioned me.
I was recently married so I obviously said no but tried to soften that as much as possible. You’re very attractive and if I was single…type thing.
Turns out she was with a guy, her gay friend. I could see him stink faced behind her. I put two and two together after talking to them for a few minutes. Turns out he was having trouble finding a guy and likely told her she could walk up to any dude and the street and get laid.
Told him “sorry, dude I know you were looking for another guy to fuck you tonight but not like this” and bid them a good night.
