Cultural Tip
In many Spanish‑speaking countries, direct confrontation can be seen as impolite. Begin with a courteous phrase such as "Disculpe" or "Perdón" and state the facts before expressing dissatisfaction. Using a calm tone and offering a possible solution often yields better results than a harsh or emotional outburst.
