The appropriate number of coat hangers shall be supplied to each room prior to the reception of passengers and returned to their proper storage place on the shelf in the soiled linen locker at the end of the trip after passengers have been discharged. Hangers swinging free from rods in wardrobe lockers or from hooks on walls of room accomodations cause considerable noise and are an extreme annoyance to passengers. In addition, hangers swinging free from hooks on walls result in damage to the finish. In order to avoid complaints, employees shall remove coat hangers from vacant room accomodations after departure from terminals and return them to their proper storage place.
