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

"When visiting Ypres, it's important to respect the local customs and traditions to avoid any cultural faux pas. Firstly, remember that punctuality is highly valued in Belgium, so always try to be on time for any appointments or meetings. Avoid discussing personal matters or asking personal questions when you first meet someone, as Belgians tend to be quite private. When dining, 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 multilingualism, so don't assume everyone speaks English. Try to learn a few basic phrases in Dutch or French, the two main languages spoken in Ypres. Avoid making loud or boisterous displays in public, as Belgians tend to be quite reserved and may find this behavior disrespectful. Lastly, remember to respect the city's history, particularly its role in World War I. Many people visit Ypres to pay their respects at the numerous war memorials and cemeteries, so it's important to behave appropriately in these places," remarked another expat in Ypres, Belgium.
