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

"When visiting Ceske Budejoviceublic, it's important to respect the local customs and traditions. Avoid discussing sensitive topics such as World War II and the Soviet era, as these periods are still a source of pain for many Czechs. Don't assume that everyone speaks English. While many Czechs do speak English, especially the younger generation, it's polite to learn a few basic phrases in Czech. Avoid being loud and boisterous in public places. Czechs are generally reserved and value their personal space, so try to keep your voice down and avoid standing too close to others. Don't leave a mess behind when you're eating or drinking in public. Czechs take pride in their clean and well-maintained cities, so be sure to clean up after yourself. Avoid being overly familiar or touchy-feely with people you've just met. Czechs are generally not as open to physical contact as people in some other cultures might be. Don't forget to tip. While tipping is not mandatory in the Czech Republic, it's customary to leave a tip of around 10% if you're happy with the service. Avoid wearing your shoes inside someone's home. It's customary to take off your shoes when entering a Czech home. Don't assume that all Czechs are beer drinkers. While the Czech Republic is famous for its beer, not everyone drinks it. Avoid making jokes about Czechs being Eastern Europeans. The Czech Republic is in Central Europe, and many Czechs are sensitive about being grouped with Eastern Europe due to the negative stereotypes associated with that region. Finally, don't forget to say "Dobrý den" (Good day) when entering shops or restaurants. It's considered polite and is a simple way to show respect for the local culture," remarked another expat who made the move to Ceske Budejovice, Czechia.
