It doesn't get more Texas than this.

Two armed robbers attacked a man eating his dinner in a Whataburger parking lot in northwest Dallas. Little did the robbers know, the man was an off-duty security guard who was thoroughly enjoying his burger.

Police said the two armed men approached the diner at the Whataburger at Inwood Road and Lemmon Ave and tried to rob him early Thursday morning, according to FOX News.

The off-duty security guard was armed and shot and killed one of the robbers while the other ran away.

Police have yet to release the dead suspect's identity, but confirmed he was most certainly armed.
