The ketchup fight occurred Tuesday at a Subway inside a Walmart store in Orlando, WFTV reported. Luis Martinez said he asked for a Philly cheese steak sandwich with his usual accompaniments: "American cheese, onions and ketchup."
Lawrence Ordone, who was working behind the counter, said he was unable to give Martinez what he wanted.
"He wants ketchup on the Philly cheese steak and I have never put -- we don't even have ketchup at Subway -- I've never put ketchup on anybody's sandwich," he said.
The argument escalated, and Ordone told the Orlando TV station he "flew off the handle." He allegedly told Martinez to fight "like a man."
"He threatened to kill me in front of my wife," Martinez said.
Martinez called police, but by the time officers got to the Subway Ordone was gone. He said he was fired the next day.
Ordone was not arrested, although police reportedly forwarded the case to prosecutors.
