Never pay upfront with these money transfer apps, I’m sure that’s what happened to this guy. If not, he should’ve physically took that money back from her not really hard to do. It’s not like she had a pimp standing by to protect her.
We always get the hookers back to the room in Vegas and say we want to score some blow....if we don't like whats happening we just say fuk it lets go back to the casino....no money exchanged and lots of times you get great free shows etc.
