If you don’t wear the mask despite an order, you will put the business in jeopardy. They can be fined or even shut down. Businesses have suffered enough from the lockdowns; don’t make it harder for them.
I didn’t say I wouldn’t wear the mask into the business, but that doesn’t mean I have to like it or accept it as you implied. The Government is putting the onus on business to enforce what is unenforceable.
