A Subway employee was fatally shot and another worker was critically injured after an argument with a customer "about too much mayo" on his sandwich, police said.
Officers responded to the shooting at the downtown Atlanta gas station shortly after 6:30 p.m. on Sunday, according to the Atlanta Police Department.
During a news conference Monday, police Deputy Chief Charles Hampton Jr. identified the worker who died as a 26-year-old woman. A second employee, a 24-year-old woman, was also shot and seriously injured, police said.
A 5-year-old child was also in the restaurant at the time of the shooting but was not injured, police said.
The women were taken to a hospital for treatment, where the 26-year-old was pronounced dead. Police did not release her name.
Hampton said the woman who survived was in critical condition on Monday.
According to police, a customer went into the restaurant to order a sandwich and became angry about his sub.
"There was something wrong with the sandwich that made him so upset that he decided to take out his anger on two employees," Hampton said.
Hampton said the man was upset his sandwich "had too much mayo" on it, then opened fire.
The man, a 36-year-old Atlanta resident, was arrested in connection to the double shooting, Hampton said. As of Monday, police had not released his name.
Hampton said he was taken into custody without incident.
