Fast food is a category of mass-produced, commercially resold food that places a high value on expediency of service. It is a term used in commerce to describe meals provided in packaging for takeout or takeaway and sold in a restaurant or store containing frozen, warmed, or precooked components. Fast food was developed as a business strategy to serve a huge number of harried wage employees, travelers, and commuters. Globally, the fast food sector was predicted to be worth $570 billion in 2018.
The drive-through has always been a distinguishing feature of fast food establishments. Outlets could be stands or kiosks that don’t have any sitting or shelter, or they could be fast food joints (also known as quick service restaurants).  Standardized goods are sent to each franchise company that is a part of a chain of restaurants from a central location.
