Restauranteur owes no duty to maintain safe premises

In Koontz v. Sybra, Inc., another Henry Saad masterpiece, the Court of Appeals held that the Plaintiff could not sue for the injuries he suffered when he fell in debris outside the entrance to Defendant's restaurant.  The Court held that the debris was "open and obvious", and since the Plaintiff chose to enter the restaurant despite the debris, the restaurant owed him no duty.  The injured man claimed that the restaurant and its employees owed him an independent duty to avoid leaving debris where it could injure someone and to discover and remove debris.  The Court held that no such duty exists, however, regardless of how long the unsafe condition exists--so long as it is apparent to a casual observer.
