Just because something happens and there are memos about it doesn’t mean it happens because of corporate policy. I’ve worked jobs that had memos that said “please don’t pee all over the floor and seat of the bathroom” and “please don’t throw poop covered toilet paper in the trash”. In neither case was the job or corporate policy so unbearable as to not allow enough time for proper bathroom use. It just seems there are some people that don’t understand normal / acceptable human bathroom behavior.
