Almost as good as Greenmarket food is the packaging. The environmentalist brings muslin for cheese-wrapping, the fashionista has a repurposed gift basket on her arm, and there’s a chef with a wheelbarrow-bike. We just met the most produce-specific shopper yet: She has a thermal bag for dairy, plastic containers for tomatoes and berries, ziplocks for baby salads, and regular bags for everything else. We stopped smushing peaches into our purse to watch her shop.
