You ask Amy to bring you back a burger and fries and get back to work. After finishing some very, very important tasks, you decide to stretch your legs and get the printer ink.

As you run down the stairs, Frank, the janitor, reminds you the door of the supply room isn't working very well.

With a big tug, it opens. You jam a door stopper in it to keep it open and venture into the dim room.

Your stomach lurches into your throat when you hear the door slam shut behind you.

You run to it and pry at the handle. It is no use, it is stuck. You scream for help. The hairs on the back of your neck prickle.
