While I understand the need for her to post her "rules" on her website, the tone of her wording comes across as kind of shrew-like. Fine, no need for her to explain herself - I get that some (lots of?) johns can be inconsiderate jerks. But by putting the emphasis on making sure she is not jerked around by the customer, rather than on how wonderful an experience the customer will have with her, it makes me wonder whether the session won't be mechanical and cold. A real turn-off.
Just beakin' off.
