When I was in high school the girls kept kissing the mirrors in the bathroom leaving lip prints everywhere. One day coach Richy stopped a handful of girls in the hallway and took them into the bathroom. Mr. Collins the janitor was waiting with his mop and bucket. Mr. Collins proceeded to mop the floor and then use the mop to clean the mirrors.
No more lipstick!
I suppose Mr. Collins’s union wouldn’t allow him to have the girls clean the mirrors themselves.
