Anytime I book someone who's not reviewed I figure it's a 60% chance it's not going to work out, but I took a chance anyway.  I consider these more of a social experiment than anything else.  So here's how it played out.  
I texted her, she very quickly confirmed all services, no up charges (alarm #1).  She got to the door, surprisingly, it was the girl in the pictures (or something really close).  She refused to come inside before getting paid (huge alarm #2).  continuing with the social experiment theme, I paid her, even included a tip!  So now she says that's for her showing up and it's $800 / hr........   I wish I could have caught my facial expression on camera....   excuse me?  She's now speaking very loudly, saying things like 'are you threatening me?' and all sorts of other nonsense.  After a few minutes of nonsense, I told her to get lost (I was a bit pissed off) and shut the door.  She continued yelling non sense for about 5 mins!  I'm sure my neighbors loved that hahahaha.  Eventually she left.  Hopefully I've saved others from the bad experience.
