A shooting broke out at the Little Red Barn Steakhouse in San Antonio, Texas, when a dispute occurred between a group of customers and a waiter.

The Little Red Barn is well known because the staff at the restaurant are fitted with fake guns and holster accessories. 

However, on Wednesday a real gun was brought to play when a verbal fight escalated to violent nightmare. An unidentified witness saw a group of male customers blame their waiter for messing up their order.

“The customers mentioned that he messed up their order, so when the waiter went to the side to step back, one of the customers got loose and started beating on the waiter,” the witness said.

She then said that the waiter left the situation and returned with a gun.

“All I saw was a black gun, cocked it back, went up in the air and shot,” the witness also said

Another patron at the restaurant caught the scary incident on camera. In the video, when the gun is fired, customers and staff members can be seen running and screaming.

Police were called to the scene, although the customers involved in the assault fled. San Antonio police are currently investigating the incident and have said that the customer who physically assaulted the waiter and the waiter could both face charges. No arrests have yet been made.
