A Tennessee woman opened fire inside a Burger King drive-through window after apparently being furious at the waiting time, police said.
Surveillance photos show the unbalanced customer leaning through the open window of the Memphis cafeteria while wielding a black gun.
In an image released by police on Friday, the woman holds the gun in both hands and points it into the drive-through window.
Police said the woman stopped at the restaurant on Tuesday and started arguing with workers because she thought her order was taking too long to complete.
She then took the gun from her car and fired several shots at the officials, the police said.
Employees fled through the back door and left unscathed.
The cops were looking for the distraught patron. A reward of up to $ 1,000 is being offered by Crime Stoppers of Memphis and Shelby County Inc., for information leading to an arrest.
