 Further marketing techniques were implemented to change McDonald's from a sit down restaurant to a fast food chain.They used such things as turning off the heating to prevent people wanting to stay so long, fixed and angled seating so the customer would sit over their food promoting them to eat faster, spreading the seats further apart so being less of a sociable place to dine in, and giving their customers branded cone shaped cups forcing them to hold their drink whilst eating which would speed up the eating process.Other companies followed McDonald's strategies to turn their own restaurants into fast food establishments, in the 1950s, including Burger King and White Castle.
