These people need to be excluded from society. Just ignore them. If you have one working for you, fire them. If one by change is an acquaintance (obviously can’t be a true friend) then cut them off - block their phone number, defriend them on social media if you use that crap, and so on. Make these people pay in loneliness.
Same with the airlines. I had a flight attendant tell me to pull mine up when barely half a nostril was showing. I couldn’t breathe. These people should be kissing the rearside of those willing to fly and patronize their businesses. American Airlines actually announces to paying customers that if you don’t wear the mask properly then you will be escorted off and never allowed to fly American again. Not good customer service for the ones willing to get back on planes and keep their crap airlines afloat. Also, no beverage service. Again, they should be kissing our feet for showing up.
