Albert De Barros, 54, was charged with battery after the sandwich commotion, which escalated at a Subway in Stuart, Florida, on 9 January.
Police were called to a “disturbance” at around 5pm at the restaurant.
The employee told Martin County Sheriff’s officers that the incident occurred due to Mr De Barros becoming “upset with her after finding out his sandwich was not separated,” according to an arrest report obtained by Fox Business.
The Subway customer and the employee had a “brief verbal exchange” that led to Mr De Barros causing a “disruptive” scene, the report said.
After this, the employee said she would no longer serve him, at which point Mr De Barros made a phone call.
While on the call, Mr De Barros allegedly picked up his sandwich and threw it at the employee, which struck her in her mid-to-lower body, the outlet reported.
Mr De Barros then marched out of the sandwich shop. The employee who was allegedly assaulted followed him, capturing a video of him, his “demeanour”, and his licence plate.
The alleged sandwich slinger was questioned by police and told them he "believed he threw the sandwich at the counter instead of the worker," the affidavit reportedly said.
Police said they saw surveillance footage from the store, which showed Mr De Barros taking his sandwich from the counter and hitting the employee with it.
Mr De Barros was booked into Martin County Jail but was released on Wednesday after posting a $1,000 bail. Records obtained by Fox Business show he will be arraigned on 1 February.
In June 2022, a man was arrested in Atlanta after being accused of fatally shooting a Subway employee because there was “too much mayonnaise” on his sandwich, WSB-TV reported.
Melvin Williams, charged with murder, among other counts, was denied bond in November while awaiting trial.
