Cultural Tip
In Brazil, many service providers (hotels, airlines, gyms) have a 48‑hour cancellation rule, but the exact wording can vary. Using “pelo menos” sounds natural and polite. In very formal contexts, you might replace “tem que” with “é obrigatório” or “é imprescindível”. Remember to keep the tone courteous, especially when you’re the one asking the other person to follow the rule.
