When my mom was dying in the ICU after a fall last year, the same day she passed, I remember waiting in line at check in at the hospital in front of someone like that. There was a woman in an American flag hat (of course) behind me huffing and tsk-ing and she literally started GROWLING like a lion (I am not kidding). She said "grrr" out loud. The she started yelling about how HER RIGHTS were being infringed upon, making a massive scene. All because she had to wait in line 2 minutes to be checked in with a picture ID and put on a mask rather than walk right into a hospital without anybody bothering to know who she was.

I don't know what it is, but being asked to take basic precautions in a hospital apparently turns these people feral.
