Cultural Tip
In many Spanish‑speaking countries, especially after recent environmental regulations, plastic bags are no longer free. Cashiers will often ask '¿Necesitas una bolsa?' to see if you really want one, and they may charge a small fee. Answering 'no, gracias' is common if you brought your own reusable bag.
