Hello,
You should contemplate about the problem and then think of ways by which you can solve it in a peaceful manner and thereby setting an example for others.
You can take few suggestions for the problem mentioned in your query-
• As the monitor of class, it is your duty to be responsible about students, inventory and things related to your class. So since your teacher has asked you you would first go to the canteen manager and understand the issue in detail and also about the students who were responsible for it. Afterwards you will go to the accused students and will question the students about their role in causing the problem. Since they are your classmates you think good of them and you I'll try to make them understand that causing harm to others and their property isn't a quality of good Student. Also you will ask them to act like a responsible student of the school and you will further ask them to be sorry for their misdeeds and apologize to the canteen owner and also pay for the damage they have done if any.
Thank you.
