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

"In Mikulovublic, it's considered rude to speak loudly in public places, especially in restaurants or on public transportation. Avoid discussing sensitive topics such as religion and politics, as these can be seen as intrusive and disrespectful. Do not assume everyone speaks English. While many Czechs do speak English, especially in tourist areas, it's polite to ask if they speak English before starting a conversation. It's considered impolite to refuse food or drink when offered by a host. If you have dietary restrictions, it's best to explain them politely. Czechs value punctuality, so try not to be late for appointments or meetings. Do not leave a mess when you are in public places, as Czechs take pride in the cleanliness of their cities. Avoid making jokes about the country's communist past, as it can be a sensitive topic for some Czechs. Do not call the Czech Republic "Czechoslovakia". The country split into the Czech Republic and Slovakia in 1993. Tipping is customary in the Czech Republic. It's common to round up the bill or tip about 10% in restaurants. Avoid wearing inappropriate clothing when visiting religious sites. Modest dress is expected in churches and other places of worship. Do not take photos of people without their permission. This is considered rude and invasive. Avoid being overly familiar or touchy with people you've just met. Czechs tend to be reserved and value personal space," mentioned another expat when asked about moving to Mikulov, Czechia.
