Yes fair comment.
So you have to chat with her first, and then if you pass the test it's £250 per hour! So that could turn into quite an expensive meeting, as I would imagine the chat could take quite a while as she asks a multitude of questions prior to agreeing to BB!
I know it's subjective, but I think she's really attractive, and surprised she's prepared to risk her health when surely she can attract as many punters as she needs without offering BB?
