My beef with public restrooms, other than the things previously mentioned is the door handles. It always has you pull to exit. Well, so many people don't wash their hands, I don't wanna pull on that nasty handle. I usually use a paper towel. It would make tons more sense to have the door push out so you can use your arm, or something clothed to open the door.
Of course, I'm the germ-freak who carries the hand sanitizer all the time and flushes with her foot
