The nightmare began like a normal everyday chore: grabbing a couple of things on my way home. It's been hours. No exit, just endless shelves everywhere ..and that thing hiding in the shadows, waiting.
Endless hallways with food? You can eat all you need, use the bathroom and never run into your own poop, just keep on walking. Sounds like a win.
Maybe throw that little guy in the shadows a pickle or two, he'll probably leave you alone after that. He probably just can't open the jar with his murder claws (I assume he has murder claws)
