Wonder if women's public restrooms are the same? Mistress?
One problem is that if a person does create a mess, there are few choices for cleaning it up by yourself. Wonder if some cleaning supplies were left accessible if people would take it upon themselves to clean up? If I were responsible for the cleanliness of a public restroom, I'd conduct a little experiment and leave obviously available cleaning supplies around and see what happens.
