They say that you shouldn’t go to the grocery store hungry. I understand the logic behind that old adage but isn’t that when buying provisions is the least tedious and the most fun? Every aisle holds so much potential for deliciousness. Plain old broccoli sounds utterly mouth-watering. Bananas feel magical. Bread could make me faint. (Well, that’s always the case.) Hungry supermarket cruising is exactly what credit cards are made for.
