It doesn't look like much, but this spoon/bowl combo was a satisfying dining experience. Not long ago, I visited a college cafeteria that had several different stations, each with a different kind of plastic cutlery. Someone suggested that I use a plastic spoon from one station with a bowl from another, because they had observed over time that the inside radius fillet of this bowl perfectly matched the outside radius curve of the spoon. This way, your spoon always scraped the corner of the bowl clean. They had gone so far as to make sure there was always a supply of spoons at the the other counter, to make sure they could use them with the mis-matching bowl.
