I'm not a mask wearer either but that's kind of a crappy response to a business asking you to wear one. Here in Oklahoma there are cities that have threatened to revoke a business's license if they don't push it. They'd be forced to close just because they don't enforce the mask rule. So to treat the business like it's all up to them is just wrong. It might be different where you're at but that's the case here.
They are doing the same in OR via OSHA. However LE will not enforce any COVID EO provisions. So what you have are a bunch of 20 - 30 yr old brainwashed low skill, low attainment types that feel they have a bit power by telling people - "you have to wear a mask".
Business needs to be smart enough to inform patrons (repeatedly) of the requirement but also not put themselves in a position of enforcement. Locally OSHA hasn't enforced anything since the first week or two. However the low attainment crowd that likes power have become zealots in Leftist enclaves.
