I went back to university as a mature student. Our prof was like 15 minutes late and some "did you know if the prof is 15 minutes late you're legally allowed to leave?" Chatter started.
Me, the ornery old man of 26 had to explain to the teenagers that they're adults now and they can leave whenever the fuck they want. It's about choices now, not compulsion.
Except for a fact that the 15 mins rule absolves you from consequences from not being there - where absences can impact your grade. So far so, that some less important courses can get you a passing grade simply from going to the lectures.
I will forever remember when an incompetent, misogynistic neurologist expressed utter shock when I ended the appointment.
I reported him before I even left the hospital, and amazingly--miraculously!--, I got a message from him a couple of days later wherein he was taking my issues much more seriously.
K-12 education and other obligations have reinforced the social norm of enduring and sitting through uncomfortable circumstances due to fear of punishment or reprisal.
Is it so shocking that the behavior drilled into people continues to pervade their norms?
I don't know if that's fair. Scheduling is not left up to the doctors, for the most part. Being an hour late is terrible and I would also be very frustrated by it, but that could be because he had a patient or two before you whose issues were much more serious or complicated than they seemed to be during scheduling.
I don't know. I see this from both perspectives, having been a patient of dozens of doctors at this point. It's not always their fault. It's not even usually their fault.
In the US at least, almost all doctors have total ironclad control over their schedule.
Source, worked 17 years in a mutli-hospital system that also had over hundred practices.
Not saying shit doesn't happen, I just spent an hour and a half at a Vet, because they had dog it by a car come in. But it's mostly on the doctors themselves if it happens chronically.
