Joseph, you are just playing devils advocate. If it wasn’t acceptable, it wouldn’t happen. You don’t have to punish people to make it stop, you just need to make it an expectation.
When I served hot lunch the kids left the tables a wreck. They threw stuff around during lunch and left everything as it was when they were done. The teachers just took them back to class and the kitchen staff cleaned. If they were told everyday that they would leave the lunch room as soon as the tables were clear, it would have happened.
You make a bar for them to rise to. It’s not an extra special midda to clean up after yourself.
