Not A Tray To Stand On

Sheryl Crowe advised us to conserve toilet paper.  Now New York state is leading the charge against that scourge of Mother Earth, the cafeteria tray:

Scores of colleges and universities across the country are shelving the trays in hopes of conserving water, cutting food waste, softening the ambience and saving money. Some even believe trayless cafeterias could help avoid the dreaded “freshman 15” — the number of pounds supposedly gained in the first year on campus (and on all-you-can-eat meal plans). “I like not having to carry a tray around,” said Peter McInerney, a freshman here at Skidmore College, as he grabbed a midafternoon snack of an egg sandwich, pancakes and apple juice. “It makes it feel like this is less of a machine just spitting food out. It’s still not home, but it feels more homey without the tray.”

In other words it's a subtle way of controlling people's behaviour.  Ever carried a plate of hot food in a crowded cafeteria?  Another small inconvenience from the nannies.
