There are one and the same problem in many school,the dining room is not clean.Some people take it as a dump, the leftover food thrown on the table or ground. This makes the room look uncomfortable for us.
I have some suggestions,first,let more people to have good habits,we can through posters, asking students attention to their behavior, to protect the surrounding environment.Than ,let the people who drop litter to clean up litter.Let the student patrol, found litter, let them leave; clean the dining room at all people eats.
If we all do that,the dining room will be more clean.
