During the war (1941-1945) the creation of 17 million new jobs finally pulls the economy out of the Depression. Millions of married women enter the labor force. The demand for restaurant meals escalates, increasing from a pre-war level of 20 million meals served per day to over 60 million. The combination of increased restaurant patronage with labor shortages, government-ordered price freezes, and rationing of basic foods puts restaurants in a squeeze. With gasoline rationing, many roadside cafes and hamburger stands close.
For a time after the war, rationing continues and wholesale prices stay high but patronage falls off as women leave jobs and return to the kitchen. Trained restaurant personnel are in short supply. Restaurants take advantage of food service methods and materials developed for the armed services. The frozen food industry supplies restaurants with fish, French fries, and baked goods. Boil-in bags of pre-cooked entrees become available. Fast food assembly lines and serving techniques used by the military are transferred to commercial establishments.
