In North Hamerica there is a big (teehee) culture of telling patients they can't be "abusive" I recall seeing signs in hospitals and clinics and doctors offices about it, similar to signs telling people not to smoke in the building. It started with cases of patients physically attacking doctors and nurses, and probably with the reasonable notion that "doctors treat you with respect, so we deserve the same in return". Now it has become an excuse for healthcare staff to not treat people who tell them to "fuck off" in a fit of fear, or who react physically during a mental health emergency or while they are intoxicants.  My old doctors office had a sign going into detail saying that stuff like homophobia and sexism were also prohibited (this was a place that had a clinic for LGBT people and is sex-worker-positive, so I do agree with that) but I'm sure a comment like "you are a doctor so you should be a healthy role model" would get you shown the door because HEYezzzzzz.
