A Subway employee is dead because a customer decided that she had put too much mayonnaise on his sandwich.

The fatal shooting occurred at an Atlanta location of the chain. The shooter fired a handgun at the two workers—the 26-year-old woman who died, as well as another 24-year-old woman who was in critical condition after the incident. At the time of the shooting, the 24-year-old’s 5-year-old child was inside the restaurant, witnessing it all.

It’s hard to believe that something so violent could occur over a sandwich, but alas, there are some very bad people in this world. “There was something wrong with the sandwich that made him so upset that he decided to take out his anger on two of the employees,” Deputy Police Chief Charles Hampton Jr. said.

The 36-year-old suspect was arrested after a tip was called in, though more information is being gathered about who the shooter was. The suspect is a reoccurring customer who has never caused ruckus before.

Willie Glenn, a co-owner of the restaurant took the shooting as an opportunity to discuss the ongoing matter of gun violence. “I want the focus to be on the gun violence,” Glen said. “Yes, it’s a sandwich, but, more importantly, someone who failed to resolve a conflict by just walking away, having a conversation … decided to take actions into his hands, and now we have families who are devastated.”

“I don’t know what the world is coming to especially with our youth. They seem to be so hot headed,” he continued. “Everybody wants to carry a gun. Everybody wants to scare somebody with a gun. It’s scary out here.”

He also said that the two women were “model employees” for the restaurant and had only begun working three some three weeks prior to the shooting.

During a police investigation, crime scene tape was draped around the Subway. There was also a hole in the front window of the store due to the gunfire.

“It just breaks my heart, to know that someone has the audacity to point a weapon, and shoot someone for as little as too much mayonnaise on a sandwich,” said Glenn.

Police are continuing to investigate the details of this case. To hear more on what we know so far, check out the video below.
