Police in Montana accuse Shane Roe of doing something along those lines.
According to officers, Roe had a gun and tried robbing a Taco John's restaurant. Officers say when a worker refused his demands for free food and money, Roe bought a meal and sat down to eat it.
He was later busted at a motel. Turns out the weapon was an air-gun replica of a Glock pistol.
He's now charged with attempted armed robbery.
