A night shift manager at a Bronx McDonald’s was arrested Wednesday for serving a side of cocaine along with the Happy Meals, according to the New York Post. Frank Guerrero's actions came to light after police conducted a three-month long undercover investigation, which they termed “Operation Off the Menu.”

“The conduct was so blatant it would be comical if he weren’t committing a serious narcotics crime,” the city’s Special Narcotics Prosecutor Bridget G. Brennan said. “Ordering coke took on an entirely different meaning on the night shift at this McDonald’s.”

During the sting operation, Guerrero allegedly sold police $10,900 worth of cocaine in eight separate sales out of the franchise at 1600 Bruckner Boulevard in the Soundview section of the Bronx.

The eatery is usually open for late-night orders and parcels that need to be picked up through the drive-through window, however, Guerrero allowed his drug customers to enter the main restaurant, officials said.

In one instance, while attending an undercover agent disguised as a customer at the counter, Guerrero allegedly concealed cocaine in a cookie bag which he placed on a large McDonald’s order of two cheeseburgers, a soda, and fries, authorities said. 

Guerrero had allegedly stashed the drugs inside the restroom’s soap dispenser earlier that day, officials said. The undercover then sat at a booth and ate a McDonald’s meal personally delivered by Guerrero. Five other sales were conducted in the McDonald’s parking lot.

Authorities revealed that Guerrero regularly sold cocaine to buyers during his shift.

As the sting operation neared its end, authorities executed a search warrant on his home in the Pelham section of the Bronx where they allegedly seized 200 grams of cocaine and $5,300 in cash. Leidy Cabral Castillo and her 2-year-old child were inside the apartment at the time.

Guerrero had worked at McDonald’s for eight years. He and Cabral Castillo were expected to be arraigned Wednesday in Manhattan Criminal Court on multiple counts of criminal possession of a controlled substance and unlawfully dealing with a child. He will also face numerous counts of criminal sale of a controlled substance.

McDonald's has made no comments so far about the incident.

Last month, reports surfaced that McDonald's was conning its customers of their fries order. An employee revealed that the company taught them how to rip customers off their fries order and how they would create imaginary employees to blame all the mistakes on when speaking with customers.

A representative from McDonald’s cleared the air surrounding the confusion and refuted the claims. Speaking to the Sun, he said, “We believe these claims to be fictional, there are no ‘secret tricks’ and we have strict operational procedures in place to ensure that fry portions are not under-filled.Without a verified source we are unable to investigate this further. Our employees work hard to ensure our customers have the best experience possible in our restaurants, and we strongly refute any claims that suggest otherwise.”

Terri Hickey, another spokesperson for McDonald’s, told spoke to Huffington Post regarding the controversy saying, “The notion of a secret trick is absolutely false. There are strict procedures in place to ensure that fry boxes and bags are appropriately filled so our customers can enjoy our World Famous Fries to the fullest.”
