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

"When visiting Mons, it's important to respect the local customs and traditions to avoid any cultural faux pas. Here are some tips: Avoid speaking French with a heavy English accent. Belgians appreciate it when foreigners make an effort to speak their language correctly. Do not assume everyone speaks English. While many Belgians are multilingual, it's polite to ask if they speak English before starting a conversation. Avoid discussing sensitive topics such as politics, religion, and the linguistic divide between the French and Dutch-speaking regions. These topics can be controversial and may offend some people. Do not compare Belgium to its neighboring countries, especially France and the Netherlands. Belgians are proud of their unique culture and heritage. Avoid being late for appointments or meetings. Punctuality is highly valued in Belgian culture. Do not leave food on your plate during a meal. It's considered wasteful and disrespectful to the host. Avoid being overly friendly or informal when you first meet someone. Belgians tend to be more reserved and prefer to maintain a certain level of formality until they get to know you better. Do not tip excessively. Service charge is usually included in the bill in Belgium, so tipping is not expected. However, it's common to round up the bill to the nearest euro. Avoid loud and boisterous behavior in public places. Belgians tend to be more reserved and appreciate quiet and calm environments. Remember to say "Bonjour" (Good day) or "Bonsoir" (Good evening) when entering shops, restaurants, or other establishments. It's considered polite and shows respect for the people working there," remarked another expat who made the move to Mons, Belgium.
