Question of the Day: Why do you think eating or drinking is not allowed in the classroom? Why does eating or drinking not go well when working on a computer?

I think that eating or drinking is not allowed in the classroom because the teacher does not want you to. The teacher knows that this school have rats and roches and they just  want them to come out. It does not go well with computers because we may spill the snack and make a mess and break the computer.
