People don't (generally speaking) follow rules. People do what they want to do regardless of what the rules are. There is no way to police everyone in the stands. All they have to say is they are eating or taking a drink. It's just nonsense. We did have a fan kicked out of our game last week for not keeping a mask on. Plus, a football game is happening. Why should there be any requirements for mask wearing for anyone? If they didn't want to handle this in a good way, they should have not played fall sports. A town a few miles away from us had the paper publish pictures from their first scrimmage. Not a single mask, and everyone shoulder to shoulder.
It will take (god forbid) a teacher or a student dying to actually make something happen.
