Yeah, when I was in Vegas a couple years ago, I learned that there are more escorts than cabs in the city. And that's a lot of cabs! Pretty much every cute local girl you see on the strip is either an "escort" or helping to sell the services of her escort friends. The trick is to only go for girls who aren't from vegas (or aren't on the strip at 11pm on saturday.) My stupid friend kept saying "look, that girls checking you out, and that one over there too, and that one also", finally, I told him to shut the fvck up and walked right over to the girls and asked them straight up: "Are you working right now?" to which they replied "Duh!, why you do you think we are all dressed up like this?"
It was cool, they were students at UNLV and were out looking for suckers money. Can't say I blame them.
