A Tennessee man turned violent on a convenience store clerk while demanding his money back for “bad chicken.”

60-year-old David Haslet, seen in security footage video from the ExxonMobil gas station where it happened, told cops that he’d been sold bad chicken by the clerk on Friday night.

He ran up to the worker, who was sweeping the ground around the gas pumps, and chased him with the knife.

The worker tripped to the ground just a few feet away while trying to get to safety. Mr. Haslett then stood over him making stabbing motions toward the clerk’s leg before another employee pushed him away.

Other staff members kept him off until cops arrived at about 11:15 p.m., using the spray from a fire extinguisher on him. Cops found him standing in the road with the knife in his hand. He surrendered to them.

The victim suffered a stab wound to the lower half of one of his legs. He was transported to a nearby hospital in critical condition.

Mr. Haslett has been charged with aggravated assault, and remains in custody on a $40,000 bond.
