This is certainly an interesting thread. I feel that there has been a terrible misunderstanding here between Mayaa and Barney. Barney says he's been in a car accident and has recovered from a coma and his injured knee is still very sore. He was looking for sympathy and compassion from an SP and willing to pay for it. He obviously didn't find it here.
Mayaa on the other hand met a client she had never met before who to her seemed "not completely lucid". Perhaps she thought him to be under the influence of some drug. She says he started yelling at her and if this is the case it is easy to see why she felt uncomfortable and ended the session, giving him his money back. In this case, this was the professional thing for her to do especially if she felt threatened because we all know how dangerous her job can be.
To me this was a tragic misunderstanding and should not reflect badly on Mayaa.
As for Barney, I feel for you man, you've obviously gone through some rough times. You can't simply expect an SP to accept anything you throw at her though. SPs are human beings and deserve to be treated with respect! Try to be more of a gentleman next time and you may be surprised at the kindness you receive in return!
