From Wicked Thoughts, via SCSU Scholars, comes a story about a private school where senior girls were kissing the restroom mirror after putting on lipstick, leaving prints that had to be cleaned every night. Finally, the principal called the girls to the restroom.
To demonstrate how difficult it had been to clean the mirrors, she asked the maintenance man to show the girls how much effort was required.
He took out a long-handled squeegee, dipped it in the toilet, and cleaned the mirror with it. Since then, there have been no lip prints on the mirror.
There are teachers, and then there are educators.
