Have you ever wondered why the sandwich has such a strange name? It's attributed to John Montagu, fourth Earl of Sandwich (1718-1792), a British statesman and notorious profligate and gambler, who is said to be the inventor of this type of food so that he would not have to leave his gaming table to take supper. He ordered meat between two pieces of bread, the idea being that his hands wouldn't get greasy from the meat and stain the playing cards. Others, who were as addicted to gambling as Montagu, seeing that, would then say to the waiter whilst pointing at Montagu's plate: "Get me a sandwich."
Somehow, "bring me a Sub," just doesn't have the same ring to it.
Sandwich is a UK town in the county of Kent.
