if you were in Vegas and a hot chick approached you (a pro) and wanted $500, but you settled on $200 and on the way to the elevator she was texting furiously to God knows who (which in hindsight should have been a huge red flag) and then, upon entering the hotel room, she quickly darts into the bathroom and locks the door where she remains for 10+ minutes.

Then, when she finally comes out, she points her camera phone at you, takes your picture and says if you don't give her $500 right now, she's going to say you raped her and call the police.
