A Subway worker has been after an argument broke out about mayonnaise.
Brittany Macon, 26, was identified as the dead woman while a 24-year-old is in a critical condition.
A customer is said to have flown off the handle at a restaurant in Dowtown Atlanta, Georgia, at around 6.30pm on Sunday.
The manager of the store fired back at the suspect, resulting in a shoot out in the car park and another worker was injured.
The injured worker’s five-year-old son was in the restaurant at the time and saw what happened.
Store owner Willie Glenn said: ‘Believe it or not, it was about too much mayonnaise on his sandwich. He decided to escalate the situation and from there, that’s when all hell broke loose.
‘One of the young ladies who was [injured] today, her son was in the store. She had a young son that had to witness all of this.’
The child is just five years old and will receive counselling, Deputy Police Chief Charles Hampton Junior said.
He added: ‘I don’t know what the world is coming to especially with our youth. They seem to be so hot headed.
‘Everybody wants to carry a gun. Everybody wants to scare somebody with a gun. It’s scary out here.”
A 36-year-old suspect has been arrested but his identity and the names of the victims have not been released.
