I hope you learned your lesson, never pay in advance. When I’m in Vegas, I’ll ask them to meet me in the lobby by the elevators. Ask what they are wearing. This way if she’s not appealing to you, there’s nothing lost. I know it’s a bit mean to do, but with the BS they pull, screw them. I did this in AC a few weeks ago, the girl was definitely not appealing, and my phone kept blowing up. It took a few minutes to realize to block the number.
