When I was a newish domme I got heavily into super intense verbal humiliation. My rates were much lower then, and I still routinely offered half hours. A SIGNIFICANT portion of my clients were men who would book half an hour of nothing but verbal and be out the door by the 20 minute mark. They very much did NOT want aftercare. They didn't even want their last ten minutes! They didn't want to sit around and chat, they didn't want to get to know me in any other context, they just wanted me to yell at them and then they wanted to GO.

Obviously it was very difficult to get a gage on their emotional state because of this. I suspect a lot of them had shame around their fetish and wanted to forget about it the second they were done. I think for some of the others scurrying out with their heads hanging in shame was an enjoyable part of the fantasy.
