A master carpenter doesn’t use plywood for the back of a hardwood cabinet even though no one is going to see it. The carpenter will know, and doing it “right” matters because that is the mark of a master. This is the stamp of quality. Rare as it may be, this obsession with quality can be found in every industry and across every imaginable product and service; however, you have to look hard to find it, sometimes peering behind the cabinet, as the metaphor implies.
