This week, Round the World is honoring the People Who Keep Us From Starving: the grocery store workers. And we don’t just mean the cashiers, but also the people who stock the shelves and mop up spills and keep everything clean, with honorable mention going to the truck drivers who bring food in to our little remote corner of paradise. Join us as we go down our shopping list at the same time that we elucidate today’s Proper Grocery Store Etiquette.
