Apparently, posh people in the UK (and for all I know everywhere else) have what, technically, is a form of sandwich. It consists of: bread, cut very thin; buttered (with butter, not marge (not even Stork)) to about twice the thickness of the film of a soap bubble; filled with cucumber, sliced just thick enough for the eater to detect the crunch, but no more; cut into small triangles with the crusts removed. This obviously requires a great deal of skill, but IMO it should be treated as a demonstration of the sandwich-maker's art, like for example an apprentice's master-piece (no pun intended!) which shows that s/he has now acquired all the expertise necessary to join that happy few, the Guild of Sandwich Makers, rather than something simply to be stuffed into the chinless faces of Hooray Henries and Henriettas in the Queen's back garden.
