Specialized forms of service involve serving customers where they are located rather than in a conventional dining area. This includes services like room service, lounge service, hospital tray service, and airline tray service. Room service can vary from basic tea and coffee to full meals served in hotel rooms. Floor service staff are responsible for taking orders and delivering meals to rooms. Hospital tray service aims to deliver nutritious meals to patients on time and attractively. Airline tray service provides meals and beverages on flights, with more extensive options on long-haul flights.
