In some schools, the mess after class is a problem and it does cost money to clean.
You're going way overboard.

I don't think I am missing the point. Maybe I am, but...
They went overboard, so I went overboard.
Say a dog urinates on the carpet. If you try to rationalize with the animal by saying "no", "bad dog", you may get the dog to stop doing it, but it is highly unlikely. What is more likely to happen, is the dog will continue to urinate in the wrong spot. Now instead, if you rub that dogs face in it, it will probably stop. Or it will at least think twice about urinating on the carpet before it does so.
Well completely killing all food and drink in the classroom is rubbing the students face in the carpet. It is extreme, but will probably be effective. However, the students are not dogs, and should not be treated as such. They could implement it temporarily, and that may be as effective.
Yes. Yes. It costs money to clean up after these students. It costs money to do most everything. We could start to analyze a lot of different things, and see how damn expensive it is to do them. I'll give you an example.
I hate it when people do not wash their hands after using the restroom. These people (I have no facts to back up what I'm saying) may be spreading germs. I might get sick because an indivdual uses the restroom, does not wash their hands, touches a door which I open, and then I touch my eye. Should we enfore mandatory hand washing? Should schools fine individuals for not washing their hands? Second hand smoking is such a problem... yet "second hand" germ contamination is overlooked.
All I'm saying is that they need to be reasonable... and I think banning food and drink from a classroom is NOT reasonable. Maybe it's just the caffeine addiction talking

But I can't imagine making it through some classes without my travel coffee mug, and a strong cup of the good stuff.
