Lisa Fulmore, 40, revealed her 20-year-old son’s chilling comments while describing exactly what led up to Monday night’s shooting that left a 23-year-old fast-food employee clinging to life.

“I talked to my son with the cops. My son is just saying that he gotta do what he gotta do and the [victim] came after him and whatever happened, happened,’’ she said.

The mom of three boys said the incident unfolded after she ordered McDonald’s on her mobile app and went to the Bedford-Stuyvesant eatery around 7 p.m. to pick up her food, which included fries.

“The fries were cold,’’ Fulmore said. “I asked the girl to change the french fries because the fries was cold. She went to the french fry machine for maybe 10 seconds and brought back fries, so I thought they was new fries, so I had left.

“So I taste the fries, and after I got to the third one, it was a cold fry still. So I went back to take the food back.

Lisa Fulmore, the mother of a man in custody for the shooting of the McDonald’s worker, revealed the details of the incident to The Post.

“I asked her, ‘Why would you give me the same fries and just put one or two on top to make me think that you gave me new fries?’ She started laughing, and all of them started laughing, acting like it’s funny,’’ Fulmore said.

“I was like, ‘What’s funny? I paid for food, and I should get what I asked for.’ They laughed at me.

“One of them was like, ‘All of this over fries?’ So now I’m arguing with them back and forth.
The boy where they cook the food at was like, ‘You got all this food in your teeth,’ ” Fulmore recalled — referring to the worker who was later shot.

“So I said, ‘You wanna take it out? You’re saying I got all this food in my teeth, you wanna take it out?’ ”

The 23-year-old employee was shot after he argued with the shooter, a customer, about his fries being cold.

Fulmore said she asked to speak to their boss and the workers said the manager had stepped out.

“Everybody started laughing again,’’ she said.

“This is when I was on the phone with my son. I was like, ‘They in this McDonald’s playing with me.’ I was like, I got kids their age, I’m not going to sit here and keep arguing with these little kids.

“He was like, ‘I’m coming down the block.’

“I was like, ‘All right.’ … Then I told him, ‘No, don’t come to McDonald’s because I don’t want you to get in trouble,’ ” the mom said.

But she said her son was already at the restaurant.

“He was like, ‘I’m coming in.’ So he came in. He heard them saying stuff to me, so he was like, ‘You all gotta back off my mother.’

“My son said, ‘Come outside’ to the boy in the back,’’ she said, referring to the worker who was later shot.

The employee didn’t exit the restaurant at that point, and Fulmore said she then told her son to just leave “because I didn’t want him to get in trouble.

“So I’m thinking my son was gone,’’ she said. “I’m thinking it was over because my son left the store.”

Then 10 or 15 minutes later, the male worker came over to Fulmore asking, “Where your son at?,’’ the mom said.

She said she told him her son had left and to mind his own business.

But “he went looking for my son,’’ she said. “The next thing you know, maybe like 10 minutes later, you hear a gunshot. So I ran to the door. I said, ‘Who’s shooting?’ ”

She said someone replied, “Your son.

“I looked, and I seen a boy on the ground, and then I saw my son running the other way. I called 911, and then I sat there and waited.”

When asked if her son had a gun, the mom said she didn’t know, adding, “I don’t even know if my son did that,” referring to the shooting.

Family and friends of the McDonald’s worker sat outside Brookdale Hospital on Aug. 2, 2022, as they awaited news of his condition after he was shot.

“The only thing I know is that my son was arguing with the boy and the boy did go out looking for my son.”

She said the victim changed his shirt at one point, “and he had something under the blue shirt, that’s why he put the big blue shirt on.”

Law enforcement sources said the victim had no prior arrests and there is no indication he was carrying a weapon when he was gunned down.

But Fulmore, referring to the victim said, “There was no reason for him to go outside looking for somebody.

“Whatever happened outside, you caused that to happen,” she said.

Fulmore’s son is in police custody but has not been charged in the shooting.

He has been previously arrested several times, including for grand larceny in 2019 and assault and theft of service in 2018, police sources said. He also has numerous sealed arrest cases, they said.
