In graduate school I swabbed a public toilet seat and wiped the specimen in a Petri dish. My cohort swabbed the bottom of their shoe and did the same. The public toilet specimen grew virtually nothing. The shoe specimen grew the equivalent of a rainforest in bacteria.
LMAO, I was like what the fuck is bathroom carpet, then I got the joke. It's a joke right? Please.
Unfortunately not, some areas of the US have nasty ass carpet all the way up to the toilet.
2 of the rentals I've lived in had bathroom carpet.
Rentals.
Student accommodation..
They were probably 40% vomit, 25% filth, 25% jizz and 10% actual carpet.
"No shirt, no shoes, no service". You get kicked out of most places if you don't have shoes.
Toilet seats are naturally smooth and bacteria have a hard time staying on the surface. Most public toilet seats have an additional antimicrobial coating.
