Fair division?

Yesterday, when I came home from the grocery store and was putting my dairy products, etc... into the refrigerator, I realized what a fair distribution of the refrigerator my roommate has given me. There are three shelves - she has two of them. There are two drawers/vegetable bins - she has both of them. There are two shelves on the door - she has both of them. Yes, that certainly seems fair. It's not so much that she won't give me any more room, it's that she has SO much food in there that it takes up all that space, leaving me with only one shelf. I kind of don't get how one person has so much food (the refrigerator is the tip of the iceberg - don't get me started on the pantry). I have seen whole families with far less food in their refrigerator. Keep in mind that we've only lived in this apartment since May 1st and that about 90% of its contents got moved from her previous refrigerator. Moving perishable food, especially that much of it, has to be a big no-no of moving.
