When you need to use paper plates, the cheap ones are too thin to hold food and the thicker ones are expensive for a second serving of one dab of potato salad. I just hand each person a stack of 10 cheap paper plates. Most often, only the top one is dirty for the light eaters so I only need to toss the top plate.
The chow hounds with the heavy steak knives may soil the top three and they are tossed. The extra paper plates in the pile give the support necessary for food.
I hear the recycle people do not want dirty paper plates. Nor do they want envelopes, staples, or spiral binders because of problems with recycling.
