One of the backbones of this game is the difference between the haves and the have nots. Gear, money, cars, whatever. I think it would be great to add a layer of that to the game in the form of food going bad the same way a corpse does. Maybe depending on the food, it goes bad faster but has a higher nutritional value? Something like soyonuts, for example, might never go bad, where as a nice new york steak wouldn't last much more than a few hours in the hot digi-sun without taking on a greyish hue, flies, etc.
This would serve to further illustrate what certain characters were okay with doing, and others would turn their noses up at. A poor, down-and-out mixer would probably still eat that day-old steak, I mean c'mon! Real meat! Whereas a corpie wouldn't be caught dead taking a bite.
Functionally, the items would go through a few stages of disintegration for a given period of time before disappearing entirely. Maybe at the later side of decay they actually make you sick? Temporary hit to endurance? Maybe the tougher and stronger you are the more you can handle bad food?
