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

"It is important to be respectful of local customs and traditions when visiting Bruges. It is considered rude to be loud or disruptive in public places, so it is best to keep conversations at a reasonable volume. Additionally, it is important to dress modestly when visiting religious sites, such as churches and cathedrals. It is also important to be aware of the local language and to avoid speaking English in public, as this can be seen as disrespectful. Finally, it is important to be mindful of the local customs when it comes to tipping, as different countries have different expectations," remarked another expat in Bruges, Belgium.
