I'm always amazed by people who can't understand a "CLOSED" sign.  There's no other information yet the concept of "closed" escapes them.

The copy shop was previously open 24 hours a day.  Corporate decided to cut costs by closing at night.  New hour signs go up on top of this I made a poster sized "CLOSED" sign.  At night when we'd close I'd shut off about half of the lights and hang the sign up next to the door.  Half the lights were on so I could finish work and then shut everything off when I left.  I'd be in the back doing something and I'd hear someone pulling on the locked door, knocking, pulling again.  I'd look at the security camera and you'd see people walk up, pull on the door, look to the right and see the sign, knock, pull again, repeat.
