According to a news report, a certain private school in Victoria recently
was faced with a unique problem. A number of 12 year old girls were
beginning to use lipstick and would put it on in the restroom. That was
fine, but after they put on their lipstick they would press their lips to
the mirror leaving dozens of little lip prints. Every night the
maintenance man would remove them and the next day the girls would put
them back. Finally the principal decided that something had to be done.
She called all the girls into the restroom and met them there with the
maintenance man. She explained that all these lip prints were causing a
major problem for the custodian who had to clean the mirrors every night.
To demonstrate how difficult it has been to clean the mirrors, she asked
the maintenance man to show the girls just 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 hasn't been any lip prints on the
mirror.
