Friend of AHT Joe DiStefano reminisces about his high school job at White Castle over on Slashfoods:

But it wasn't all burnt grills and onion dust. One of the perks was eating sliders during our breaks. To mix things up, I'd invent off-menu items: double cheeseburgers with the middle bun removed, double fish, fish and chicken, triples and so on. After years of topping my burgers with onion rings such improvisation was the next logical step.
