If you were a teacher, how would you feel being constantly interrupted by students munching on chips and having to clean up all of the trash that they left? I would want to quit my job! However, there is a better alternative; not allowing students to eat or drink in class. Students shouldn't be allowed to eat, drink, or chew gum in class because it's very messy, some students have food allergies, and it's rude. Any teacher who decides to be generous and let their students eat will regret it. This will warn teachers about the consequences beforehand so that they won’t have to regret anything.
First, it's very messy. It will be like a cafeteria; students will leave trash and spills everywhere, and obviously stick gum under desks and chairs.
