Like Thomas, I can only speak for myself. I have never gotten truly angry during a paid session, even ones that did not go well (although I have gotten frustrated). But, I also have never had anyone force me past my stated limits in that context (well, I have but it was always with a buildup & a kevel of consent in the very end).

However, I have gotten angry with a couple of Dommes (all of whom were pros who had extended our relationship into more personal service) when they either put me in a compromising position that was beyond my stated limits in that area or just pushed me too far down the pain path even though we had multiple conversations specifically about that.

My experience is that in a Pro/client setting, Dommes tend to pay much more attention to my limits and I always feel more comfortable saying no when I am paying rather than when it really is about what she wants. Which leads me to allow more before finally being pushed past the brink where anger arises.
