Isaac Stein has launched his self-deprecating “Shysters Dogs” while furloughed from his full-time job at the Internal Revenue Service (IRS), NPR reports.

The hot dog stand proudly advertises itself as “the only honest ripoff in DC”.

Having originally planned to sell hot dogs on weekends to fulfil a childhood ambition, the US government shutdown enabled Mr Stein to take on the new project seven days a week.

The only two menu items at his stand are a “correct hot dog” or a “hot dog with the wrong toppings”.

Mr Stein said: “I’m trying to incentivise people to do what I think a correct hot dog is, which is mustard and sauerkraut.

“If someone wants other things, that’s totally, totally fine. No judgement. But I do reserve the right to assess an additional dollar as a penalty.”
