Take the filthiest bag into the store and set it on the conveyor belt to have your things bagged. Then, the person behing you (preplanned) objects to the filth and demands the counter be sanitized with sanitizer like they demand in restaurants. Hey, it’s their rules. Put a little Alinsky in everyones life.
Not really the rules of the people you demand to clean it. They may well be as against the nanny laws as you are.
