I had the inconvenience of having dinner at Quincy House today, where they've taken the iniative of removing trays from the dining hall. I haven't yet found out whether this is a long-term change, or just something that was happening this weekend, but here's a breakdown of the advantages and disadvantages of a trayless system:
HUDS - Advantages
HUDS - Disadvantages
Students - Advantages
Students - Disadvantages
HUDS makes no secret of the fact that the goal is primarily to save money. HUDS' director, Ted Mayer, told the Crimson last month that when there are no trays,
"People take less food. They take less food and they waste less. They’re a bit more conscious of their choice. And it also saves money, and if you save money, you can use it for buying more local or sustainable food."
To be honest, it is quite doubtful that the money saved will go towards buying sustainable food. More likely, it will go towards HUDS' bottom line.
You don't often see Harvard students gaining weight on the HUDS regimen. So trying to scrimp on the meals that students paid for by encouraging them to take less food than they need for proper nutrition — is just a bit unscrupulous.
