Don’t mind my ass in your food, ma’am

I think I was at school, and needed to use the bathroom. I walked to where the womens bathroom was, and saw no mens one. I walked around a bit, looking for one. Down a floor in a restaurant, there were tables that looked like fancy toilets, although had noplace to sit, had no walls around them, and were in the middle of the eating area. I walked up to one and started to sit on it when I realized there was food all over it. I buttoned my pants back up and continued my search. A woman told me there was a mens room downstairs, so I hurried down there. They were doing construction down there and removing pipes. I held my breath to avoid breathing in dust and probably asbestos. I came across a mens shower room looking thing and was happy to have finally found it. There were guys in a steaming shower, and another guy on a toilet. Again, no walls. I walked into the toilet area and nearly sat on a jacuzzi thing. I saw the water go deep underneath and a seat on the other side. “Not the toilet” I said, and jumped onto the real one.
