> I bet you close the bathroom or stall door when you poop though.

I do, but not because I'm shy someone might see (a glimpse) of me being naked; I do it so that they don't attempt to enter a toilet already in use. I find myself often not closing the toilet in after hours. In fact, I don't close the toilet at home cause I know the people who can enter won't. Except when I poo, I might, because I don't want them to smell it.
