We all talk about how we want our Ts to be consistent and reliable. We expect the absolute most from them. Shouldn't that work both ways?

When I said you're committing to paying for more than one appointment, I mean by being an ongoing client you expect your T to have an appointment for you and therefore you theoretically committed to paying for it. If you want your T to keep a standing weekly slot open then, yes, you are committing to coming weekly, surely? If you change to every two weeks, then that would be different.

I don't think it is outrageous to have a cancellation policy. I still don't know why this bugs me quite so much.
