I agree, and yet it seems to be very challeging to enforce, there's a lot of students that never abide by the rules no matter how many times you tell them, it seems like a continuous struggle, and also we have to walk a very thin line between enforcing the rules and alienate the students, I talked to some student about that, some told me we really want to follow the rules, but sometimes we barely make it to the class for a lot of reasons, and we have to put something in our stomach, and we can do that without missing a good portion of the class, so have to take it the class
