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

"In Cadzand, it's important to avoid being late for appointments or meetings, as punctuality is highly valued in Dutch culture. It's also considered rude to interrupt someone while they're speaking, so try to wait your turn in conversations. Don't discuss personal matters or ask personal questions in public, as the Dutch value their privacy. Avoid making loud noises or drawing attention to yourself in public places, as this is seen as disrespectful. When dining, don't start eating until the host or hostess starts. Also, don't leave food on your plate as it's considered wasteful. Lastly, tipping is not mandatory in the Netherlands, but it's customary to leave a small tip for good service," remarked another expat who made the move to Cadzand, The Netherlands.
