Sugar Fiend Stabs McDonald's Customer After Coffee Sweetener Tiff

A 57-year-old McDonald’s customer's coffee run turned bloody when an irate diner stabbed him at a Manhattan outlet following a spat over the amount of sugar in his coffee.

On Tuesday, Edmund Pieters stopped by the McDonald's on Eighth Avenue near West 35th Street after a doctor’s appointment and encountered a screaming and unruly diner. At the time, the latter was complaining to the manager and other workers at the eatery that his coffee did not have enough sweetener. When Pieters intervened, the assailant attacked and stabbed him in the chest, NY Daily News reported.

Pieters told the daily: “He was screaming at the manager, the people in back, everybody. He was making a real scene.”

“He was arguing about sugar in his coffee,” recalled Pieters. “Of all things, he wanted four more sugars. He kept going back for sugar. What did he need with like 15 sugars?”

According to the report, the diner employees refunded the suspect’s money even after he finished his coffee but still, he yelled, "I’m not satisfied."

Pieters said the security guard looked frightened during the incident. “I could see it in her face. She was telling him, ‘you gotta go.’ I went up behind him because he was [pretending] like he was going to hit her. She was jumpy.”

“I said ‘you’re not going to touch her,’” Pieters told the man. “‘You gotta go.’”

Pieters said that he followed close behind the security guard to see the suspect out.

But outside, the sugar addict challenged Pieters, "'What do you want to do? Come on. Come on,'" Pieters recalled him saying. However, the security guard intervened and threw the first blow.

The assailant retaliated by drawing out a knife and stabbed Pieters. After the stabbing, the man fled the scene.

"He tried to get me in the heart. An inch more and I would’ve been done," Pieters added while speaking to the Daily News.

An ambulance took the victim to a local hospital for treatment, the New York Post reported.

Police reviewed the surveillance footage and are now looking for the assailant. The suspect is described as a bearded man with glasses. He was last seen carrying several tote bags.

Police are urging anyone with information regarding this incident to call NYPD Crime Stoppers at (800) 577-TIPS.
