<p>My son starts college next week, and I just checked pictures of his cafeteria and saw LOTS of trays. YES! I think the no-tray idea is ridiculous, for all the reasons posters have already given. This is one thing in our world that actually works well, so why mess with it? Certainly our high-tech engineers can figure out a way to wash a tray that doesn’t take 1/2 gallon of water. And if our college students are made aware of the extra cost of food wastage, I’m sure they can respond in a positive way.</p>
