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

"When visiting Brnoublic, it's important to respect the local customs and traditions to avoid any cultural faux pas. Czech people value their personal space, so avoid standing too close to someone or touching them unless you know them well. It's also considered rude to interrupt someone while they're speaking, so wait for your turn to talk. Czechs are generally reserved and may not respond well to loud or boisterous behavior, especially in public places. They also appreciate punctuality, so make sure to be on time for any appointments or meetings. When dining, remember that Czechs usually keep their hands on the table and pass dishes with their left hand. It's also customary to say "Dobrou chu?" (Enjoy your meal) before eating. In terms of tipping, it's customary to leave around 10% of the bill if you're satisfied with the service. However, always check the bill as some restaurants include the service charge. Avoid discussing sensitive topics such as religion and politics unless you know the person well. The Czech Republic has a complex history and these topics can be sensitive. Lastly, Czechs are proud of their language and although many speak English, making an effort to learn a few basic phrases in Czech will be appreciated," said another expat in Brno, Czechia.
