Navy, Army and Air Force Institutes

The Navy, Army and Air Force Institutes (NAAFI ) is a company created by the British government on 9 December 1920 to run recreational establishments needed by the British Armed Forces, and to sell goods to servicemen and their families. It runs clubhouses, bars, shops, supermarkets, launderettes, restaurants, cafés and other facilities on most British military bases and also canteens on board Royal Navy ships. Commissioned officers are not usually supposed to use the NAAFI clubs and bars, since their messes provide these facilities and their entry, except on official business, is considered to be an intrusion into junior ranks' private lives.
NAAFI personnel serving aboard ship are part of the Naval Canteen Service (NCS), wear naval uniform and have action stations, but remain ordinary civilians.
