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

"In Tavira, Portugal, it's considered rude to rush a meal. Portuguese people take their time to enjoy their food, so try not to hurry your dining experience. Avoid discussing politics and religion, as these topics can be sensitive and may lead to heated debates. It's considered impolite to interrupt someone while they're speaking. Wait for your turn to speak and listen attentively when others are talking. Don't be too loud or boisterous in public places. Portuguese people are generally reserved and appreciate quiet and calm behavior. Avoid wearing beachwear or revealing clothes in the city or when visiting religious sites. It's considered disrespectful and inappropriate. Don't forget to say "please" (por favor) and "thank you" (obrigado/obrigada) when necessary. Portuguese people appreciate good manners. Avoid being late. Punctuality is valued in Portugal, so try to be on time for appointments or social gatherings. Don't refuse food or drink offered to you, as it can be seen as disrespectful. If you really can't eat or drink something, politely decline. Avoid making negative comments about the country or its people. Portuguese people are proud of their heritage and may take offense to such remarks. Don't leave a tip on the table in restaurants. Instead, tell the waiter how much you want to leave when you pay the bill. Avoid calling someone by their first name unless you're invited to do so. Use formal titles like Senhor or Senhora until a more informal relationship is established," said another expat in Tavira , Portugal.
