One told me recently that a guy started choking her, until she grabbed his privates and twisted hard. He soon got the message.
Another story - two guys arrived and one wanted to sit in reception and wait for his mate while he had a massage. She said no because they don't want someone hanging around and maybe stealing stuff like the eftpos machine or who knows what else while the girls are all busy. So they both got abusive and left.
I'm respectful and nice to the girls and occasionally this has resulted in extra services at no extra cost. I haven't asked for more, she just did it. One girl gave me a bj when it wasn't included and when I asked her afterwards about it she said "you are nice" and she mentioned a lot of customers aren't.
