> I've lived and spent my time in major cities most of my life. I've used many public urban bathrooms. Like many things in cities, they are used much more heavily and often are less clean. Some have been disgusting in places, but I've never seen what you imagine.

I'm not op. I've been in public restrooms smeared with faeces.
