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

"When visiting Mechelen, it's important to respect the local customs and traditions to avoid any cultural faux pas. Here are some tips: Belgians are known for their punctuality, so try not to be late for appointments or social gatherings. It's considered rude and disrespectful. Avoid discussing personal matters or asking personal questions when you first meet someone. Belgians tend to be private people and it may take some time before they open up to you. Belgians are proud of their languages, so don't assume everyone speaks English. Try to learn a few basic phrases in Dutch, which is the language spoken in Mechelen. Don't compare Belgium to its neighboring countries, especially the Netherlands and France. Belgians are proud of their unique culture and heritage. Avoid discussing politics, especially issues related to the linguistic divide between the Flemish-speaking north and the French-speaking south. When dining, remember to keep your hands on the table (but not your elbows), and wait for the host to start eating or drinking before you do. Belgians are known for their excellent beers, but avoid getting drunk or behaving in a disorderly manner. It's considered disrespectful and inappropriate. Lastly, tipping is not mandatory in Belgium as service charge is included in the bill. However, if you received exceptional service, feel free to leave a small tip," said another expat in Mechelen, Belgium.
