I have a cousin who's been gleefully exploiting gun laws to avoid masks. State doesn't require them here, but individual businesses still can-- and some chain stores have been quite obnoxious about it. But the law says if you're carrying a firearm, you can't cover your face (think bank robbers). He has a CCL, so now when pushy door greeters ask if he has a mask he replies "No, but I have a gun". They can't legally make him comply...
