Triage. He already is not acting responsible
I agree - that is my reading of the situation.
If people like BlackAgnes, & I, can put up with being wheeled into the hospital - even though one merely had a fall or a faint, and already felt well enough to walk - but were told to stay on the stretcher - then why can't this doctor?
It is well known that Doctors make the worst patients. They cut corners, hide symptoms, give accounts of their situation laced with medical language to influence those who hear them, and often believe themselves to be outside the rules of quarantine.
