true story. my son has a bit of a phobia for public toilets and one day I was out with him and his sister in the city, riding ferry etc. I could see around lunchtime he needed to go, but he refused as he usually does. after lunch it was obvious he really needed to go and wouldn't make it back home in time (1.5 hour train ride plus time to get back to the station). there was a nicish public toilet at Manly Beach and I walked him in, he had agreed to try as he was clearly desperate.

but he decided no he couldn't go.

so we catch the ferry back to Sydney. again I asked to take him into the toilet as it was quite nice, but he refused. as we got to the train station, there was no excuse. he was bursting. had to go and had no choice. took him into the toilet. it was without a doubt, handsdown, the worst I had EVER been into. there was shit in the floors, smeared on walls, on the frikken toilet seats. piss everywhere. he had no choice. thankfully there was toilet paper.

I cleaned the seat as best as I could with toilet paper. he went.

we disinfected the shit out of both ourselves when we finally got home.

As for OPs question, some people are just plain animals
