Is this Really Necessary?

I wonder what sort of problems led to this bathroom sign. I saw this
in the medical center where I have been waiting for Kate to get an
MRI. Of course issue #1 is the "napkin" verbage, which I'm not going
to bother thinking about.

The real question is what sort of person assumes that restrooms at
home are DIRTIER than a public restroom? I, for one, am proud to
declare that my home bathroom is cleaner than this one.

Well, except for the napkins on the floor...
