Just grossed out

So I've been at the ER with my mother in law for the last 6 hours and finally she had to pee so of course they need a sample. No sample cups so the nurse had to go get one, then go get a toilet hat because my mil doesn't have the strength or coordination to pee in the cup. So we are standing there waiting for the toilet hat and she looks down and there's dried blood spatter on the floor and wall and what looked to be dried urine. I'm just so grossed out right now. I understand it's an ER, but seriously that is the most disgusting I've ever seen an ER bathroom. I have to pee so bad now I'm just like, fuck it, I'll hold it, I don't want to pee anywhere in this building.
