There are both advantages and disadvantages about the phenomenon that college students order takeout food. Its advantage lies in the convenience and quickness of take-out, that is, you can get a box lunch directly after class, instead of waiting in line in the dining hall all the time, and sometimes you even have to wait for more than half an hour when there are many people. This will take up personal time to a certain extent and waste more time that could have been done. Also, going to the canteen can reduce the smell of lampblack. The bad thing is that some of its quality and some food safety problems have not been well guaranteed, and there are some hidden dangers in food safety. Moreover, the fast food box for take-away will also have a certain impact on the environment.
