It’s a scenario that is all too common: You finish your meal in the Dining Commons and pick up your plates and cups. As soon as you enter the dish drop-off area, you are overcome with the thick and suffocating smell of who-knows-what. With a low droning sound, the conveyor belt rattles against tipped-over cups. The sides of the belt are splattered with sauce, milk, yogurt, coffee and sticky fluids; crumpled tea bags, pieces of food, stray forks and soggy napkins litter the space. Accidents happen, but this is a disaster on its own level.
