Over half the folks I see with masks leave them gaping open at the top such that the nose doesn't even come in contact with the the mask. This isn't wearing a mask, it's dangling a fashion accessory and pretending to technically meet the rules. It's intentionally conspicuous neglect.

There was one of these in an enclosed area Orrery and I also had to sit in.

I asked him to put it on correctly and he tugged it up to appear to cover his nose then looked away... and it dropped back down to below. So I asked him again. He did the same thing again.

Orrery told him to pull it up. He said he'd been vaccinated, so why did we care? (The CDC recommends folks still wear masks in public after vaccination.)

That's when somebody-definitely-not-me had had enough. They walked up to the guy, stood with their mouth a foot from the dude's ear, and screamed at near top volume, "Put. On. Your. Mask!" Not the best move, and it might technically count as assault, but I know I'd call it defense of self and others. Still, not the greatest.

To his credit, he didn't really flinch... but at least he left the room. I'm sure they stubbornly refused to learn anything from it, though, and I'm sure that somebody-definitely-not-me is somewhat uncomfortable with having snapped like that.

But still, that must have been very, very cathartic for them.
