Bingo!
All throughout grade school we had to clean the classroom before we left, put our chairs on the desks so the janitor could do a quick run through for stains or whatever.
We had one janitor for 40 rooms, cafeteria/gym and offices. We all did our part and no one thought of it as work, it was just being responsible.
