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

"When visiting Alexandroupoli, 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 of food or drink can be seen as rude. Always accept with a smile, even if you're not particularly hungry or thirsty. Avoid discussing sensitive topics such as politics, religion, and the country's economic situation. Greeks are very passionate about these subjects and it can lead to heated debates. When visiting churches or monasteries, dress modestly. Women should cover their shoulders and knees, while men should avoid wearing shorts. Don't rush or pressure Greeks. They have a more relaxed approach to time and schedules, which can be frustrating for visitors used to punctuality. Avoid making the 'moutza' gesture, which involves extending all fingers and presenting the palm towards someone. This is considered a serious insult in Greece. Don't compare Greece unfavorably with other countries, especially Turkey, as there is a long history of rivalry and conflict between the two nations. Lastly, Greeks are proud of their culture and heritage, so showing appreciation for their history, food, and traditions will be well received," mentioned another expat when asked about moving to Alexandroupoli, Greece.
