It's like the old story of the dog who gives up chasing the rabbit.... the dog's buddy mocks him for not catching the hare. Dog says "I was running for my lunch, he was running for his life".
These places are trying to stay in business. Like it or not, they have rules they need you to follow to keep operating. It's no burden to assist them in their endeavor, but failing to help them risks them being closed down, or worse yet, called out publicly in today's cancel-culture. They are running for their lives, you are running for your lunch.
I'm on the side of "I don't care if it's scientifically sound, I'll do what it takes to help places out and not give any grief to the people who are about to cook for me".
Heck, I went in a Golden Corral this past weekend... from the woman at the door requiring masks AND seeing to it everyone hand-sanitizes before getting three steps in the door, to the masks, patrons needing gloves, table spacing, etc..... not only do I have no problem with it... I PREFER it. The only thing negative about the experience were the groups of people who clearly took the "f--k you, I ain't gunna do it" path.
Again.... the anti-maxskers are the Karens in cases like these. Karens want special rules and special treatment and are more than happy to tell you what they will accept, regardless of the written and unwritten rules of behavior of the people they are near.
