Yours sounds very well organised to me! Mine has three shelves, and the top one is completely filled with jars of jam, chutney, pickles etc. I hardly ever use any of them, but when I go through them periodically I don't like to throw out the ones that are still in date.
There are more permanent occupants in the middle shelf - mayo, tomato ketchup for my sister (bleuch), pickled onions (yum!), spreadable butter, 'real' butter, cottage cheese, other cheeses and sometimes veggies that won't fit into the veg drawers (cabbage, broccoli, celery, the occasional large lettuce). These seem to take up about half of the available space on that shelf, duh...
Then if I've actually been shopping I might add things like bacon, the occasional pie, very occasionally a cheesecake, chicken etc. If I've made a large batch of soup or similar I have to try to shove everything around to make space for the bowl.
I always feel better about my fridge when it's a little emptier. I like the sound of yours.
