How the automatic doors at Wal Mart open from both sides. You can exit through the enter doors and enter through the exit doors, AND PEOPLE DO!. Probably 2/3s of the foot traffic I've seen go through the wrong f*cking door. It simply enables stupid
I'm a nice guy, I hold the door open for women/children/elderly and step aside and let them pass when going through a choke point, but when I'm going through the door at Wal Mart and some idiot is coming through the same door from the wrong side, I pretend they don't exist and just keep walking.
