When visiting Madrid, Toledo, Porto, and Lisbon, it is important to note that the Spanish and Portuguese value politeness and respect. When dining in Spain, rounding up the bill is appreciated, but tipping is not as common as in the United States. In Portugal, tipping is not obligatory, but leaving a 5-10% tip is a courteous gesture. In terms of dress code, modest and conservative attire is typically expected when visiting churches or religious sites. When exploring local markets or shops, bargaining is not typically expected but can be considered in certain situations. To fully embrace the local customs and etiquette, it’s always best to learn a few basic phrases in Spanish and Portuguese and greet locals with a warm “buenos días” or “bom dia”.
