I've posted this before, but the hair touching is possibly the only thing that will make me stop whatever I'm doing and ask them not to do it. My hair is long and thick, I don't wash it that often and not only does touching it make it dirty and greasy, trying to run fingers through it doesn't work and it hurts - when I get asked what I don't like, it's the only thing I say.
That's before we come to the ones who shove their fingers up your bum or have a wank with lube all over them and then shove them straight in your (invariably newly washed) hair. I'm usually quick enough to get out the way but not always, and I've had to dig my nails into my palms and count to ten before just to stop myself knocking them out
