Eating out or eating at home. please help me to correct them

Some people like to eat out at reastuants or fast food stands,while others prefer to eat at home.It depends on their lifestyle. Some people have very busy jobs and don't have time to cook. They like the convenience of eating out.Overall, it is cheaper and healthier to eat at home.
The cost is rising up when we are eating out, especially with friends. I can buy lots of vegetables in the market with the same amount of money that it costs. for example, if I spent seven or eight dollars for my lunch at a fast food stand ,it is enough to feed two more people at home.
Eating at home is better for us. It is a wasted of money to always eat at restaurants, they serve more food than what I need for one meal, and most of time I need to pack the rest up and bring it home. If We eat at home,we can cook what we want using our own ingredients and flavours, and control how much food we need.
However It is convenient for us to eat out at fast food stands, it saves our time, we don't need shopping, cooking and cleaning up.But there is a lot of simple food that we don't need to take a long time to make.If we eat out, we need to drive, park, and wait at the table for service, then drive back. I prefer cooking and eating at home because of the health issue. Everyone needs to make choices for their lifestyle.
