What the hell? No offense, but was this in a slum somewhere or something? Not saying it doesn't happen in other places, but I think I've came across that once in my ~35 years, visiting countless of public bathrooms, cities and towns, admittedly mostly around in Europe, South America and Asia, but still...
I don't think that's a "city" thing, that might be very local to the specific city you visited, or the specific area.
