A baker's dozen is 13 items, not 12, a tradition from medieval England where bakers added an extra loaf to avoid severe penalties for selling short-weighted bread, ensuring they met strict weight laws and preventing fines or beatings. This extra item served as a safety margin, a customer incentive, or a quality check, making it a long-standing practice for 13 items in a "dozen".
