The first one does sometimes take her shoes off to tuck herself up into her chair.
The second one does not.
I keep my shoes on as I would never be comfortable around the therapist without them on. How would I protect myself in shoeless feet?

I do however lean on and sit on tables while teaching. I have no problem eating on a table someone else, who was clothed, sat on. The students are generally in clean clothes and appear washed. I might feel different if I taught in a nudist law school.
