Yesterday morning, at the Rockaway Deli & Grocery in Queens, a customer apparently lost it and stabbed two employees. According to WABC 7, Ortho Arnold is seen on a surveillance tape getting his change and then spitting in the cashier's face: "As other nervous customers start leaving the store, Arnold pulls the knife." The victims, the owner's son and cousin, were able to fight him off with broomsticks. The owner said Arnold is a regular customer, "He's a little crazy. I mean, he does sometimes some things that are not normal." Arnold, who faces assault charges, claimed the blood from the victims was his own and that he acted in self-defense.
