Greetings These are important. In Spanish-speaking countries, greet people you encounter with buenos días (good morning), buenas tardes (good afternoon) or buenas noches (good evening). Use bom dia,boa tarde and boa noite in Brazil.
Shops Always greet people when entering and exiting a shop.
Cheek kissing When meeting people socially, give besos (kisses) on the cheek (both cheeks for Brazilians). Men shake hands.
Shorts Dress for the occasion; for example, only tourists and athletes wear shorts in Buenos Aires.
Photographs Ask before photographing people, particularly in indigenous communities – payment may be requested.
