"I got all the permits in late September, and then I was furloughed on October 8th," Stein said.

So with his newly free time, the side project he started before the shutdown turned into a seven-days-a-week gig. It's a simple menu: a "correct hot dog," or a "hot dog with the wrong toppings."

"I'm trying to incentivize people to do what I think a correct hot dog is, which is mustard and sauerkraut," Stein said. "If someone wants other things, that's totally, totally fine. No judgment. But I do reserve the right to assess an additional dollar as a penalty."

The rest of the menu is similarly cheeky, including RC Cola (which Stein thinks is the best cola), MoonPies, dog treats and branded stickers. He offers a 5 cent discount for customers who "briefly recite the historical significance of MoonPies and/or RC Cola." Also available on the menu: "SHIRT OFF MY BACK".
