Cultural Tip
In Brazil it’s common to offer help right away, especially in customer‑service roles. While “Precisa de ajuda?” is perfectly polite, many Brazilians prefer the slightly more informal “Posso ajudar?” when speaking to a peer. In the South of Brazil you’ll also hear “Precisas de ajuda?” (informal tu), but it’s rarely used in most urban areas.
