Yes, but the old lady's car would still have been blocking the drive-thru window. Fast food restaurants have internal policies -- designed to comply with their insurance policies as well as with prudent legal advice re liability -- against serving pedestrians through the drive-thru window. If the woman was blocking the window, thus creating a situation where it could not be used to serve the growing line of customers behind her whose food was ready without their getting out of their cars and walking to the window, the officer was right to arrest her after she refused the manager's request to move her car.
