. Fast food refers to food that can be prepared and served quickly.
Yes fast food is a meal ready to serve for some time but it slow for the wait. For example, the order pizza and sit at the restaurant, we will have to wait for the pizza for about 20 minutes and between us of course we have to spend time when the long wait we are more hungry. The very hungry, we order food a lot and we need to pay up again. So fast food is not ready in the concept of me.
