When the Expo East folks say they want to cut down on waste at the show, they mean it. I went to pitch my mini pizza box from lunch (I know, I know), and was soundly reprimanded when I threw it in the trash receptacle. A prim-looking woman, who was apparently overseeing the area, reached in, grabbed my pizza box from what was nearly the bottom of the bin, and tossed it in a box labeled for compost. "Sorry, I didn't catch you in time," she said. We chatted for a minute, and then I left, making sure to avoid shaking her hand.
