A Tennessee woman opened fire in a Burger King drive-thru window after apparently outraged about the wait time, police said.
Surveillance photos show the unhinged customer leaning through the open window of the Memphis fast-food restaurant while waving a black gun.
In one image, released by police on Friday, the woman holds up the firearm with both hands and aims it at the drive-thru window.
Police said the woman came to the restaurant on Tuesday and got into an argument with workers because she felt it was taking too long to complete her order.
She then took the gun from her car and fired several shots at the staff, police said.
The employees fled through the back door and were unharmed.
The police were looking for the deranged patron. A reward of up to $ 1,000 is offered by Memphis and Shelby County Inc. Crime Stoppers. for information leading to an arrest.
