Mark Phipps was employed as a cashier at a Clark gas station. A customer drove into the station and asked him to pump leaded gasoline into her 1976 Chevrolet, an automobile equipped to receive only unleaded gasoline. The station manager told Phipps to comply with the request, but he refused, believing that his dispensing leaded gasoline into the gas tank was a violation of law. Phipps stated that he was willing to pump unleaded gas into the tank, but the manager immediately fired him. Phipps sued Clark for wrongful termination. Clark contended that it was free to terminate Phipps, an employee at will, for any reason or no reason. Decide. [Phipps v Clark Oil & Refining Corp., 396 NW2d 588 (Minn App)]
