Culture
Greeks take great pride in their history and culture, and they judge politeness based on actions rather than words. Additionally, there is a casual atmosphere; everyone is regarded as a cousin. They frequently make gestures with their hands. Enjoy doing this. Speaking politely too much can occasionally come out as pretentious to the person you are speaking with. It's nice to learn common phrases like "please" or "thank you" (pah-rah-Kah-LOH).
Greeks typically believe that it is polite to let the stranger initiate contact. If you take the initiative by saying hello first, you're likely to find that people suddenly become friendlier. You might feel neglected when entering a café or passing a gathering of people on the street.
Women's shoulders must be covered and both sexes' knees must be covered according to church dress codes. Due to the sheer volume, this is usually only lightly enforced during the busiest part of the summer travel season! In any event, churches and monasteries, especially those with high tourist traffic, typically have appropriate clothes available at the door. Simply grab it as you enter and drop it off as you leave.
