I don't see any reason to keep a buffer intentionally. If she moves and my hand slides somewhere she doesn't want it, I don't let it linger or try to use it as an excuse to put it there myself later, but otherwise it's on her. If for example she's standing up in front of me & I have my hand between her legs, but down by her thigh and she decides to sit in my lap at that moment she's got no right to be upset that there's contact with her pussy. Again, that doesn't mean I get a free pass and leave my hand there or try to finger bang her or that it's okay for me to intentionally put it there later. But that contact that she caused with her movement is on her as long as I promptly move away. If you were following the "move slow enough to give her time to brush it off" rule, and she wanted more buffer zone she should have brushed you off sooner to keep her DMZ intact. This changes if you were the sudden mover and her movement was reactionary and evasive but had unintended consequences, in that case it's on you for not giving her time to react before you crossed into the no-go zone and she'd have every right to tell you about it. But that's not what you describe.
I could be reading the world scolding a little too literally, but if I was scolded for such I'd probably go ahead and wrap things up and move along. I'm not gonna get all butthurt about it, I'd still tip and say thank you and what have you. But a dancer that is distressed by incidental contact she initiates isn't one I want to spend more time around. And she'd probably write me off as a creep who got upset with her because she stopped me from touching her inappropriately.
