A Florida man just wanted ketchup on his Philly cheesesteak sandwich at Subway. When he didn't get it, a confrontation with the sandwich maker ensued, leading to a 911 call.

Now-former Subway employee Lawrence Ordone told TV station WFTV he was working behind the counter at the sandwich restaurant in an Orlando Walmart on New Year's night, when a man ordered a Philly cheesesteak.

"He (the customer) wants ketchup on the Philly cheesesteak and I have never put -- we don't even have ketchup at Subway -- I've never put ketchup on anybody's sandwich," Ordone told WFTV.

The restaurant chain -- famed for its "$5 footlongs" and diet commercials with "Subway Guy" Jared Fogle -- does not offer ketchup, according to a menu on the Subway website. Only condiments like mustard, mayo, vinegar and oil are available.

When the customer, Luis Martinez, rejected the ketchup-free sandwich, another customer in line offered to buy it, WFTV reported.

It's disputed what exactly happened next. Ordone claims Martinez mouthed off to the customer, so he came around the counter, and he told WFTV he felt threatened when Martinez said he had "something" for him and walked toward his car.

Martinez claims Ordone threatened to kill him in front of his wife and called 911, WFTV reported.

"I was scared," Martinez told WFTV. "Next thing, I'm thinking a gun's going to come out."

By the time the police arrived, Ordone reportedly had fled the scene.

Whatever the details, Ordone said he regrets his actions that led to his dismissal. "You can go buy your own ketchup, and I promise to God, you can put as much as you want on it and nobody's going to say nothing," he told WFTV.

A spokesperson at Subway's corporate headquarters did not immediately return NBC News' request for comment Friday.
