Red Riding Hood.
All the better to eat you with.
It was lunch time now. Red always ate her meals inside her room. The guards deemed it unsafe to let her leave and the doctors decided she was uncurable, so they just slide the trays of food through a slot at the bottom of the door. The tray had a bowl of some sort of gruel, a loaf of bread, a bottle of water and plastic utensils. Five mintues after they slide in the tray, the slot reopens and she slides the tray back out. The entire meal is completely eaten and the bottle empty. This has been going on for about 2 years now. The guards try to spend as little time of around the room because it gave them the creeps.
