If your spouse drags you into a store and you are bored out of your mind you can always play the "how many people can you get to de-mask" game. On the few occasions I have been approached for not wearing a mask I have tried to see how long it takes for some Karen/asst manager to pull their mask down - it always happens. They will say something to me and I'll say "pardon?", then "huh?", and so on until I have to basically tell them I can't understand them through their mask. When they take it off and say you are supposed to be wearing a mask, tell them that they aren't so why should you? I haven't had anyone blow up on me yet, but be near a door just in case.
