How is maintaining public restrooms a "massive liability"? Surely its an inconvenience but massive liability seems a bit of a hyperbole.
Try hiring someone for a job where the job could sometimes be cleaning up bodily fluids and odors in a bathroom. Even the government deems it infeasible. Or, think about how much someone would have to pay you to do that job.
And, honestly? If more people had to clean toilets in use by other people, maybe we wouldn't have so many folks expecting other people to clean up after them. I see countless posts in my Facebook group about trash on the street. In the time it took to take a photo and post it to social media, they could have picked up the trash and taken it to a nearby bin.
But I suppose that experience goes two ways. Some people think they're above the human condition, to the point where they won't even clean up after themselves, even in their own homes. And other people recognize that it's actually not that hard to clean things up, if you just do it. We all have good and bad days.
