Samantha Brown works in the receiving department of a leading publishing company. She has become good friends with many of the suppliers. At 6 P.M., John Smith delivered a truckload of art supplies. John was in a hurry and asked Samantha to accept the order. He promised that everything was there. Samantha signed the receiving report without verifying the specifics of the order. Two weeks later the art department called complaining that their department was being charged for items they never received. The accounting department has already processed the payment to this vendor. If you were Samantha's supervisor, what would you do in this situation?
