The one I see actually did this for me because of how strongly opposed I was to committing. I actually would call one way or the other, and several days in advance, because just not showing up felt rude to me (see, even I have a line in terms of how I interact with those therapist people). It did sort of help me and even now when I quit and go back, my regular time has been there. I do it less now, so I guess it was not a disaster like for the woman in the example. I would have had a raging fit and quit if the rules had changed on me.
