Big difference for me between dancing because one is getting paid to do it, and dancing (even in the same clothing) because one selected that outfit, herself, and just chooses to do it.
They are getting paid very well because management benefits as many, many customers are getting focus directly on her. She needs to be worth MORE than the $450 that the business is "investing" for such brief periods of time. Hence, I would be absolutely leery of the "no strings attached" - $450 for 15-30 minutes. I have a hunch that she's not being quite honest with your DS about what "else" she does. Either that, or she hasn't been fully "vetted" yet...
If he regards her as a girlfriend, I would suggest that he pay a visit - and stay a while...my brother had a very similar experience with a girlfriend years ago. Things weren't as simple and cut and dry as she had suggested. It got messy, ugly, and there was quite a bit more to her little deal than she had let on.
As for my own girls, I would never want them to think that anything comes so easily to them with no strings attached. I want my kids to learn that they can take pride in doing something that they're good at and earning a living at it - something that they don't have to use euphemisms or lies to describe to relatives...
