RADNOR, Pa. (CBS) — A worker at a McDonald’s on the Main Line was serving up more than a happy meal, police say.

Investigators say what he is accused of doing in the parking lot was illegal and now he is facing serious charges.

According to investigators, the worker, identified by Radnor Police as 29-year-old Allen Trammell, was allegedly selling crack cocaine in the parking lot of the restaurant on Lancaster Avenue while he was on the clock.

Investigators say Trammell was a street level dealer who through word of mouth may have been making upwards of $1,500 a week by selling dime bags of crack cocaine.

Police say they made four undercover buys before taking Trammell into custody on numerous drug charges.

When he was arrested, police allege he had 57 bags of crack cocaine in his possession and more than $150 cash.

Radnor Police Lieutenant Andy Block says Trammell has been employed at the fast food restaurant for about two years.

“When not working as a crew and preparing food, he was out in the rear parking lot selling crack cocaine. So in a sense, it can give you a new definition of what may be considered a happy meal,” Block said.

During a news conference Wednesday, Block said there is concern that Trammell was working in food preparation while handling the drugs.

Block says there is no indication that drugs were sold either over the counter or through the drive-thru window.

Court records show Trammell, going back to 2005, had two drug dealing convictions and served time in prison. When we asked the owner-operator of the McDonald’s for comment on the arrest and whether background checks are performed, she emailed:

“As an independent owner/operator I take allegations such as these very seriously. However, it would be inappropriate for me to comment upon either a pending police matter or any employment-related matters.”

Customers say they were shocked to learn about the drug charges. Neither the suspect nor his legal representative was available for comment.

Police say Trammell was employed at the restaurant for the past two years and his alleged drug dealing had been going on for the past six to eight months.

Trammell, of Philadelphia, was unable to post his $100,000 bail.
