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

"When visiting Rethymno, it's important to respect the local customs and traditions to avoid any cultural faux pas. Here are some tips: Avoid showing too much skin when visiting churches or monasteries. Greeks are generally conservative, especially in religious settings. Women should cover their shoulders and knees, while men should avoid wearing shorts. Don't refuse food or drink offered to you, as it can be seen as disrespectful. Greeks are known for their hospitality and it's common to be offered food or drink, especially when visiting someone's home. 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 discuss politics unless you are very familiar with the situation in Greece. The economic crisis has been a sensitive topic and it's best to avoid it unless you're sure it won't cause offense. Avoid using the 'OK' hand gesture (forming a circle with your thumb and index finger), as it is considered vulgar in Greece. Don't rush or push in lines. Greeks value patience and it's considered rude to rush or push ahead of others. Avoid littering. Greeks take pride in their beautiful country and littering is frowned upon. Remember to say 'please' and 'thank you'. Greeks are polite and appreciate it when visitors make an effort to use basic Greek phrases. Avoid making noise during siesta time, usually between 2pm and 5pm. Many businesses close during this time and people often take a nap. Finally, don't assume that everyone speaks English. While many Greeks do speak English, especially in tourist areas, it's respectful to learn a few basic Greek phrases," said another expat in Rethymno, Greece.
