Canteen messing was in place before Jago's Mansions called in someone from J Lyons I think to sort out the messing shambles. General messing came into being for Shore Establishments and Capital Ships with Cooks as a non sub rating to carry out those duties. Officers Cooks were a non sub rating before that I think. Canteen Messing for smaller vessels continued until the 1960's I think.Sorry, I may be getting on a bit, but since when did they become 'Chefs'? They were always cooks in my day 70/80s. chef. [shef] the chief cook, especially in a restaurant or hotel, usually responsible for planning menus, ordering foodstuffs, overseeing food preparation, and supervising the kitchen staff. So per the dictionary we have junior acting probationary assistant OD's running around as 'Chefs' before they have even seen a galley, or passed out of Raleigh. FMD !!!
