A police officer in Georgia had what is being described as a "severe break in judgment" after he apparently drew his gun on a McDonald's customer who was taking too long to receive his order.

Scott Biumi, a detective sergeant with the DeKalb County Police Department, was in the drive-thru lane of a local McDonald's last week, when he reportedly became impatient with the truck in front of him, and decided to confront the driver.

After pulling his Chevrolet Impala ahead of the truck, Biumi allegedly stepped out of the car and began hurling expletives at the other driver — 18-year-old Ryan Mash.

According to the official police report, Biumi then pulled out his gun, pointed it at the Mash's head, and shouted "you don't know who you are fucking with."

He then holstered his weapon, reentered his vehicle, and took off.

Mash, who happens to be an employee of that particular McDonald's, didn't realize at first that Biumi was a cop — he was off-duty, and was wearing plain clothes.

But a friend of Mash's noticed that Biumi was wearing a badge on his belt, and they were also able to snag Biumi's tag number before he left.

Biumi was ultimately arrested at his home in Forsyth County, and charged with aggravated assault.

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