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

"In Pardubiceublic, it's important to respect the local customs and traditions. Avoid making loud or disruptive noises in public places, as Czech people value quiet and peace. It's also considered rude to interrupt someone while they're speaking, so always wait for your turn to talk. When dining, remember that Czechs usually keep their hands on the table and use both knife and fork. Leaving your hand in your lap might be seen as impolite. Also, don't start eating until the host or hostess starts. Czech people are quite formal, so avoid addressing someone by their first name unless you're invited to do so. Always use their title and surname instead. It's also considered impolite to ask personal questions, especially about someone's salary or personal life. Czechs value their privacy and might find such questions intrusive. Avoid discussing sensitive topics like politics, religion, and the country's communist past. These topics can be sensitive and might lead to uncomfortable situations. Lastly, punctuality is highly valued in the Czech Republic. Always try to be on time for appointments or meetings, as being late might be seen as disrespectful," mentioned another expat when asked about moving to Pardubice, Czechia.
