MILL VALLEY, Calif. -- An employee at a fast food place was arrested after a customer at the drive-in window received the wrong side order with his chicken dinner -- some pot.

The customer who visited a Kentucky Fried Chicken in this San Francisco suburb Friday got two bags of marijuana, instead of the extra biscuits he had ordered. He gave the pot back to the worker, got his biscuits and called police.

Police arrested Carlos Ayala, 26, at the restaurant. The sheriff's office and the restaurant's management company did not immediately return calls Tuesday seeking further detail.
