Fast food is a type of mass-produced food that prioritizes speed of service. This commercial term refers to food sold in a restaurant or convenience store with frozen, preheated, or precooked products and packaged for takeout. Fast food was created as a commercial strategy to accommodate the large number of busy commuters, travelers, and salaried workers. In 2018, the fast food industry was worth approximately $570 billion globally. I love fast food. I spend my free time with my friends at Fast Food. My favourite food is "fast food".
