The Waffle House bathroom is tiny, barely the size of a closet, with just the one toilet in it. Strictly a one-man operation. But the lock on the door is one seriously heavy-duty industrial strength piece of hardware.

It took me a minute to realize why such a beefy lock is on the inside. Why would you need such a huge lock to keep people out of a one-hole bathroom? Because it’s the Waffle House bathroom, and it only has one hole.
