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

"When visiting Naxos, it's important to respect the local customs and traditions to avoid any cultural faux pas. Firstly, Greeks are known for their hospitality, so refusing an offer, especially food or drink, can be seen as rude. Try to at least sample what is offered to you. Secondly, Greeks are very religious, so when visiting churches or monasteries, dress modestly. Women should cover their shoulders and knees, and men should not wear shorts. Also, avoid discussing politics or the economic situation in Greece, as these are sensitive topics. When greeting someone, a firm handshake is the norm. Greeks are also very expressive and may touch your arm or shoulder during conversation, so don't be surprised by this. Avoid using the 'moutza' gesture, which is extending all fingers and presenting the palm towards someone, as it is considered highly offensive. Lastly, Greeks are generally laid back about time, so don't be surprised if things run a bit late. However, as a visitor, try to be punctual for any appointments or reservations. Remember, the key to avoiding cultural faux pas is to observe and respect the local customs and traditions," said another expat in Naxos, Greece.
