Plenty of McDonald's devotees have said they'd kill for Big Mac, but Detective Sgt. Scott Biumi may be the first to mean it. While waiting in the Golden Arches drive thru recently, the off duty cop pulled a gun on a customer in front of him when he became enraged that he was having to wait too long for his food.

The evening of April 9, high school senior 18-year-old Ryan Mash was patiently waiting on his food with some friends in the drive-thru of a Georgia McDonald's where he works. After "two to three minutes," officer Biumi, who was behind Mash's F-150 truck in his Chevrolet Impala, apparently became incensed at how long it was taking the fast-food joint to process his order. Livid, Sgt. Biumi pulled his car in front of Mash, and got out to confront the teen.

The DeKalb County Police Department officer then drew a handgun, allegedly stuck his head inside Mash's truck, pointed the firearm at the teenager's head, and screamed "you don't know who you are f***ing with," according to the official police report. Sgt. Mash then put the gun away in his holster, walked back to his car, and left.

Mash said he had no idea that Biumi, who was dressed in plain clothes, was a police officer. He said the incident happened out of nowhere.

"This flies in the face of decency and police professionalism and you can quote me on that!" said Ken Vance, the Executive Director of Georgia's Peace Officer Standards and Training Council. "His certification will be suspended immediately."

The DeKalb County Police Department has confirmed the gun Biumi pulled on Mash was his service weapon.

"We believe, right now, that it was his duty weapon, and a DeKalb-County-issued vehicle that he was in," Forsyth County Sheriff Duane K. Piper said.

Sheriff Piper added that authorities do not believe Mash or his friends said or did anything to set off Biumi.

A member of the department for 20 years, officer Biumi has since been arrested and charged with felony aggravated assault. He was released on $22,000 bail. Biumi's police certification has been suspended and he has been placed on administrative leave for the remainder of the investigation.

"It appears that he had a severe break in judgment," Piper added. "It appears that the entire situation evolved from him being angry at the time it was taking for him to get his food."

Biumi will appear in court May 23.
