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

"In Rhodes, it is considered disrespectful to refuse food or drink offered to you, as hospitality is a significant part of Greek culture. Avoid discussing politics or making negative comments about the Greek government or economy, as these topics can be sensitive. It's also considered impolite to leave a lot of food on your plate, as it can be seen as wasteful or unappreciative. When visiting churches or monasteries, dress modestly and avoid wearing revealing clothing. Women may also be required to cover their heads. It's also important to remember that Greeks value punctuality, but they also have a relaxed attitude towards time, so don't be surprised if things run a little late. Avoid making the 'moutza' gesture, which is extending all fingers and presenting the palm towards someone, as it is considered highly offensive. Also, avoid waving with an open palm, as this can be misinterpreted as the 'moutza' gesture. Lastly, Greeks are very proud of their culture and heritage, so avoid making negative comments about their country, traditions, or history," mentioned another expat when asked about moving to Rhodes, Greece.
