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

"In Carvoeiro, it's considered rude to rush a meal. Portuguese people take their time to enjoy their food, so don't try to hurry your waiter. It's also considered impolite to interrupt someone while they're speaking. Wait for your turn to speak and avoid talking loudly in public places. Portuguese people value their personal space, so avoid standing too close to someone during a conversation. It's also important to dress modestly, especially when visiting religious sites. In Portugal, it's customary to greet each other with a handshake. Kissing on both cheeks is also common, but usually among friends and family. It's considered rude to greet someone with a hug unless you know them very well. Tipping is not mandatory in Portugal, but it's appreciated. However, over-tipping can be seen as ostentatious. Portuguese people are proud of their language, so try to learn a few basic phrases in Portuguese. However, avoid comparing their language or culture to Spain's, as this can be seen as offensive. Finally, it's considered disrespectful to walk around town in beachwear. Even though Carvoeiro is a beach town, make sure to cover up when you're not on the beach," remarked another expat in Carvoeiro, Portugal.
