Tipping is appreciated but not mandatory; rounding up the bill or leaving 10% for good service in restaurants is standard. When entering churches, dress modestly by covering your shoulders. Croatians are generally direct but very hospitable. Learning a few basic phrases like 'Hvala' (Thank you) goes a long way.
