If you’re a human person, there’s a good chance you like to eat food, and probably store a bit of it in a refrigerator. You likely open the door and look in, wondering what to eat, then close the door again because you can’t see anything easy. Learn to use your cold storage like a 5 star restaurant does. Keep it cleaned out. No science projects allowed in the fridge. Store your leftovers in clear containers, and decide where to keep them so you know what to eat first. We all eat differently, but storing the ingredients so you can see them will make more efficient use of your groceries.
