A warm greeting matters: say
buenos días,
buenas tardes, or
buenas noches when entering a shop, office, or someone’s home, and use handshakes, a light cheek kiss, or a friendly
abrazo depending on how well you know the person. Mexicans often value politeness and personal warmth over blunt efficiency, so small talk, indirect refusals, and showing respect to elders or hosts are normal parts of everyday etiquette.
