Greetings
Use a firm handshake, and often a kiss on each cheek for friends and close acquaintances.
Punctuality
Social gatherings may have a relaxed approach to time, but be punctual for business meetings.
Dress Code
Casual yet stylish for daily activities; formal for business or special events.
Respect and Politeness
Use "usted" for elders and strangers initially; transition to "tú" when invited.
