Why do we quietly stress over which stall to use in a public restroom?

you could be in an airport, a restaurant or even at work. hey, when ya gotta go, ya gotta go. but if you cant get that prime toilet seat next to the wall, you just might hold it. two kinds of people in the world: “i’ll sit right in the stall next to you—i gotta go” and “i’ll just wait till the room clears because i am about to clear this room!”
