At one time there was a discussion about having a “Mess Makers Wall of Shame”. Take still frames from the video and post. The guilty are given a choice of being put on “Clean up Patrol” for 30 days or banned from the committee area for 30 days. The number goes up for repeat offenders/slow learners. This approach has been discouraged - and hence the on going problem.
The psychotic results of this could be rather amusing.
