I do not disagree that one therapist can tell a client whatever. But the client has options too. I am not as much concerned about whether a therapist will not hold an appointment with someone actively drunk or high,(I of course I would not see a therapist who felt that way, but there seem to be a mix of them ) but that the therapist got or pretended to get upset. Eff that - it is my boundary. And there are therapists to be found who won't pretend to be and who won't get all up about how much their pretend anger or upsettedness means they care. And if it is not pretend or play acting, then I think the therapist needs to get their own therapy and a client should get far away from that therapist until that therapist comes to understand it is not their place to do so.
