Horrifying details emerge after Subway worker, 26, shot dead over ‘too much mayonnaise on sandwich’

AN angry Subway customer opened fire on two employees after he complained about too much mayo on his order, police said.

The customer was reportedly left furious after being given too much of the condiment in his sandwich in the fast food chain restaurant in downtown Atlanta, Georgia, on Sunday.

After opening fire inside the store, one employee, 26, was fatally shot dead.

Another 24-year-old woman was left injured, and is now in critical condition, Atlanta Police Deputy Chief Charles Hampton Jr. said at a news conference today.

She was shot in front of her 5-year-old son who was inside the restaurant.

Officers rushed to the horror scene just after 6pm.

Deputy Hampton Jr. told reporters outside the Subway: "The suspect came inside the restaurant, ordered a sandwich, and 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 here".

Hampton said the customer then "decided to take out his anger on two of the employees" in a "senseless act" of gun violence.

Willie Glenn, one of the owners of the Subway chain told ABC News: "A customer came in and he wasn't happy with the way his sandwich was made - there was too much mayonnaise on it."

He added that he doesn't understand why the customer didn't ask employees to, "take some mayo off, or make another sandwich, or ask for a refund."

"I just never, ever, ever thought that any kind of situation would rise to that level," Glenn added.

"We've always been able to deescalate any situation. But this one just went from zero to 100 in a matter of seconds."

He continued: "Now we've got a young person who is probably going to spend the rest of his life in jail over a $7 sandwich and some mayonnaise."

Both of the employees were relatively new to the store, and had only been working there for just a few weeks.

They were described as "excellent workers" and " model employees".

Meanwhile, the co-owner has said he might close the store permanently, adding: "I can't put anybody else at risk like that in that neighbourhood.

"It's not worth somebody's life."

The 36-year-old Atlanta man has been arrested, the Deputy Police Chief confirmed.

However, his name was not released.
