I figure it is the therapist's office and they can do what they want - my decision is whether to put up with it or not after talking to the therapist about the situation. I would not care about smoking one way or the other, but did not want to go when the woman's dog was there. If the dog had been there from the beginning, I would have found a different therapist. The dog was only there on certain days - so I made sure not to have an appointment when the dog was going to be there.
I would have said something if it bothered me. Is the bothering physical (don't like being around smoke) or just the idea that the therapist was satisfying their desire or need for oral comfort during the appointment?
