Ugh. No wonder drivers don't get along with each other. Thank Zeus for having our own little rolling cubicles on wheels to mind our own business in. I've gotten stares ever since masking up since last year. But no open "challenges" from anyone having an issue with it. If someone is that upset about it, I just head back to the truck and don the FF403 instead just to rustle some jimmies.
Again, if you don't want to wear one, fine. I was already too much of a loner to be affected by any of these "activity mandates" from the get-go any way. Dined out very rarely in my life. I usually took it to go and ate it elsewhere long before it was an order.
The world will get back to whatever and introverts like myself will keep their mugs hidden.
