As the doctor started the exam, he patted her husband’s stomach and called it a “grocery tumor”.'Obesity' is a slim person wearing a fat suit that is disease.
I think the case can rest on that one.
Stepping out of the role of medical professional that way, to enter into this kind of over familiarity, when someone is in a vulnerable position-laying down- is not appropriate: boundaries.
I can't think of an equivalent, I suppose it's like this doctor suddenly patting the concave tummy of a slim person saying something like "famine".
