Do it ironically posted:

In their houses?

It's loving disgusting you're walking all over, you're in public bathrooms where people piss and poo poo on the floors, outside walking where a dog took a dump, and that's not even talking about how uncomfortable it is to have shoes on all day.

Can some american explain this to me because i'm at a loss for any sort of benefit to this, take your drat rear end shoes off at the door you don't live in a barn!
