I think there should be a sticker to buy. When you go to a business that requires you to engage in the covid B.S.. you stick it on the door saying "I would have pationized you. But for your covid cowardice".
Kinda like the "I did that" sticker for things F*d up by BeijingBiden.
A nasty Yelp report can have an effect. Local managers live and die by those. A tsunami of one-stars will at the very least prompt a "What the E'll" from corporate. Yeah, yeah, corporate is the source of most of the madness, but they get the message that business is going down. That is passed on to owners, who have totally different priorities.
Hhmm, not a bad idea there, might just wake some folks up to the reality of their actions.
