Once was a time you could only get one of Dave's famous sandwiches with a single meat. (They were called”grinders” back then by the way. Another story, another day.) When you ordered, the counter person put kitchen code on the order slip for the cook. “Heech” was a ham and cheese submarine. “Pep” was a pepperoni sub. “Sal” was, of course, a salami sandwich (and a really mean wise guy who used to come in and service the pinball machine). MB was a sloppy, wonderful, meatball sandwich, dripping with sauce and melted cheese. Occasionally, wags working at the counter would send back an order for a heech or a peech or a seech or a meech. They were soon fired. Even Dave's prodigious patience had its limits. One customers wasn't satisfied. He always wanted salami AND ham AND pepperoni. And he always ordered two sandwiches. And he came in everyday, Tuesday through Friday. The famous John Deyoung worked the counter in those days. His personal motto was “only the truly lazy are truly efficient.” John got sick and tired of writing “Heech+Pep+sal” everytime this guy came in. So one day he wrote “Jake” instead. Don't ask me why. Another of John's mottos was: “Never question genius .” And really, when you stop to think of it, does E=mc2 mean anything to the ordinary Joe like us? Nothing as tasty as the Jake, we guarantee you that.
