What cultural faux pas should I try to avoid making in Zadar?

"When visiting Zadar, it's important to respect the local customs and traditions to avoid any cultural faux pas. Firstly, Croatians are generally conservative and traditional, so avoid discussing sensitive topics such as politics, religion, and the war in the 1990s. Secondly, punctuality is highly valued in Croatia, so always try to be on time for any appointments or social gatherings. Thirdly, when greeting someone, a firm handshake is the norm. Kissing on the cheeks is reserved for close friends and family. Fourthly, Croatians are proud of their culture and heritage, so avoid making negative comments about their country or comparing it unfavorably to other places. Fifthly, tipping is customary in Croatia, so it's considered rude not to leave a tip in restaurants or for services. Lastly, when visiting churches or other religious sites, dress modestly and behave respectfully. Remember, it's always a good idea to learn a few basic phrases in Croatian, as this is greatly appreciated by the locals," mentioned another expat when asked about moving to Zadar, Croatia.
