Where I live, most of the people I see masking are working at shops which force them to mask. Almost all stores have newnmask sign on the door, almost everyone ignores it and no one says anything. The staff are just as friendly as usual and you can see when people are smiling with their eyes, even with muzzle. I see it when I make some small talk or wish them a nice day. I do see people masked voluntarily, but they are in the minority, and I've never had any negative interactions with them, these stories are bonkers to me and I've lived in places where people were much more polite than where I am now. I guess if I was confronted like that, I'd just tell them that they are free to make their own healthcare choices and I will make mine and give them a nice smile :D But I am always surprised to hear these stories and would love it people stated the general area they live (so I can avoid them)!
