Yeah, pretty much the same in Mongolia. Of course we've managed to avoid local outbreaks in Mongolia (all our cases were brought in from outside the country and quarantined on entry), so we can afford to be a little relaxed about it. While I personally think wearing a mask in a moderately-busy supermarket is prudent risk management, I also find the people yelling at the non-mask-wearers in the stores are acting like jerks. As long as somebody isn't a heavy breather and getting too close, I say just leave them be...
As for the 'Karen' meme, as far as I've read most of the people actually named 'Karen' don't take it seriously or personally. Sure it sucks a bit to have a name associated with a negative thing, but sometimes that just happens. And it certainly pales in comparison to the poor people that share the name Epstein or Cosby! 😉
