But while the environmental benefits are real, going trayless is not a panacea. At Skidmore, the all-you-can-eat format and multiple food stations, featuring vegetarian, Italian and classic comfort foods, encourage students to forage, taking a bit of this and a little of that. But this system also leads to congestion as diners return to the lines for seconds (or fourths).“That’s one of the disadvantages,” said Sam Pope, a junior from Worcester, Mass., referring to an absence of trays. “You have to keep getting up and getting more food. It increases dining hall time because there’s so much traffic.”
On the second and final paragraphs, I'm glad to see that the elimination of trays won't be considered until at least the fall, but I see little evidence that eliminating trays would reduce waste. More likely, it would just increase students' time in the cafeteria as they had to wait through numerous lines, meaning you'd have less turnover at the tables in the cafeteria, meaning you'd have more crowding.
