Cultural Tip
In many Spanish‑speaking countries there is a growing eco‑conscious movement encouraging people to bring their own containers for groceries or take‑away food. However, some stores still have policies that require the use of their own packaging for hygiene or branding reasons, so it’s always polite to ask first, as in this phrase.
