A woman in Fredrick, Maryland was offered a little too much excitement than she was looking for when she took her two kids for a special treat at Sonic.

Carla McFarland was shocked to discover a bag of marijuana mixed in with her family's drive-thru meal when she took her children, a 6-year-old daughter and 8-year-old son, to Sonic on Wednesday. According to The Frederick News-Post, as the family rolled through the drive-thru and McFarland passed her children their chicken strips and french fries, she reached into the bag for her own fries only to find a small plastic bag of what looked like marijuana.

"I just kind of sat there in my car in shock," McFarland said. "I kept thinking, what if my kids had eaten it?"

Immediately after contacting the police, the mother notified Sonic's management, who remade the meal at no charge and were extremely apologetic. "I definitely can't say that they didn't go out of their way," said McFarland. "I honestly think they were more in shock than I was."

Upon some probation, a Sonic employee admitted that her bag of marijuana must have slipped out of her apron into the bag. The fast food worker was immediately fired, with McFarland being notified about the developments. It is unknown whether the contents of the seized bag were tested to confirm whether it was marijuana.

John Louderback, the franchisee of the Sonic location, told the paper that the incident is under investigation, but refused to speak about the employee drug-testing policies of the restaurant. The case was under investigation, but no arrests had been made yet, Lieutenant Jennifer Bailey, Frederick County Sheriff's Office spokeswoman said.

After posting her experience on Facebook, McFarland's story caused some humorous attention. "I think that's why everyone thinks it's so funny, because it's marijuana and it's going to be legalized," McFarland said. "It could have been crack. It could have been cocaine in that little baggie."
