It pays to check your drive through food order before you leave the window. So, a pair of North Carolina teens discovered.

The pair was confused as to why there were three bags of food when it was just the two of them but they took the bags and left. As they were driving down the road, they opened the third bag. To there surprise, they found a bag of marijuana and a 9 millimeter pistol.

When they stopped for gas, a guy pulled in behind them and demanded the bag. They gave it to him.

The police are investigating.
