Today I did some sorting of food. I sorted packaged food from big carton boxes given as a charity, into piles of the specific type of food. I sorted frozen packaged food like Chicken, Shrimp, Sausages, Cheese, Cheese Balls and prawns into Separate. I presume it was to speed up finding them later when they get used, as there were many things to look through, and they were all randomly placed in cartons.
