The supermarkets I think are part of the reason with their butcher's section or counter and the youngster behind who they call a butcher. I doubt unless the various bits of meat were labeled half the time the lad would know what was what bit of the animal probably would not even know what animal.
Same goes for the fishmonger. It was painful when I was served last Saturday the young lad had to keep looking at the labels when I asked for various type of fish.
