Hm, I just thought of another aspect to this. Should a T apologize to a client for having to reschedule and/or thank them for being understanding/accommodating? I'm thinking particularly if it was a receptionist (not the T themselves) who called to cancel. This was often the case with MC. At first, when MC would see us next, he'd apologize and thank us for understanding. Then...he stopped apologizing, even if it was a last-minute change. I did mention this to him and said it felt like we were being taken for granted. He apologized, said he *should* have apologized for the cancellation/change and would be sure to do so in the future (I forget whether he did after that or not).

I feel it's considerate of T's to apologize, even if it was a completely unavoidable cancellation.
