Anything left in the kitchen is going to get et. The only exception would be labelled things in the 'fridge, which have to be cleaned out every week. Thankfully I'm not in the office enough to keep anything in there.

We have plenty of food and hot-drink-makings at all times. Our kitchen's weaknesses are an electric stovetop and no stored water.

An FSR in my drawer will take care of any reasonable food requirement for a day, and could easily be stretched to two or three days if I keep activity to a minimum. That's without hitting the multitude of snack bars and pogey bait stocked in the kitchen.
