Fast food restaurants and cafes are very popular all over the world. But they aren’t like ordinary restaurants.
There are no waiters. You order your food at the counter and pay for it at the same time. You can get your food in a bag or a box or a tray. You often eat with your fingers.
Drinks are all in paper or plastic cups. There are no saucers. You eat your meal, then you throw all the bags, boxes and cups away.
It’s easy. It’s cheap and it’s fast.
