Furious over the excessive amount of mayonnaise on their sandwich, an irate customer shot two Subway employees, killing one.

Officers with the Atlanta Police Department responded to a neighbouring gas station Sunday evening after receiving a 911 call that someone in the area had been shot.

In the restaurant, police found two female employees who had been shot. A 26-year-old woman died at the scene from her injuries, while a 24-year-old woman was rushed to the hospital.

Apparently, the 24-year-old employee was shot in front of her young daughter who was visiting her mother at the time of the shooting.

In response, the on-duty manager at Subway fired at the shooter, but he missed, and the shooter fled. Later, an unnamed 36-year-old man who was involved in the shooting was arrested.

In an interview with a local television station, owner Willie Glenn said that both victims had only recently started working at the restaurant.

Last week, the US Supreme Court ruled against a New York law restricting gun-carrying rights. It’s expected that more people in the US will be able to carry guns legally now, which means more guns in the hands of angry people.
