Nightshift at the Office

What's worse is the constant distant moans of countless zombies below, unable to see them in the dark. You either starve slowly or risk being eaten alive by the swarm below in an escape attempt. Hard to sleep in a desk chair with constant moans, too.

Imagine being in an office in a skyscraper during a zombie apocalypse. The zombies haven't the brainpower to track their way to you through the stairs all that way up, but you're trapped with only a slowly dwindling water bubbler.
