While on holidays in Greece, accept how things are and don’t try too much to change them, or be judgmental towards Greeks if they don’t react in the orderly and organized manner that you might be accustomed to. When you face an unexpected problem, it’s a good practice to just smile, shrug your shoulders and say “ola kala” (“everything’s fine”). Be patient and retain a good sense of humor.
Go with the general flow and mood. The mood in Greece over the summer is relaxed. People are keen to enjoy the sunshine, the sea, the blue sky, or their coffee, regardless of the problems they may be facing. Take things easy and chill out, that’s the general idea behind holidays, anyway.
Don’t try to change local people to match your expectations. Make sure that you smile often and honestly. Locals love foreigners who have a pleasant mentality and predisposition. Be polite towards people, it will take you a long way.
