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

"In Zlinublic, it's important to respect the local customs and traditions to avoid any cultural faux pas. Here are some tips: Avoid discussing sensitive topics such as politics, religion, and the country's communist past. Czechs are generally private people and may not appreciate such discussions, especially with strangers. Do not assume that everyone speaks English. While many Czechs do speak English, especially the younger generation, it's polite to ask if they speak English before starting a conversation. Do not forget to say "Dobrý den" (Good day) when entering shops, restaurants, or other establishments. It's considered rude not to greet people in this way. Avoid being loud and boisterous in public places. Czechs are generally reserved and value quiet and order. Do not leave a mess when you're eating or drinking at a pub or restaurant. Czechs take pride in their cleanliness and expect others to do the same. Avoid being overly familiar or touchy-feely. Czechs are not typically very demonstrative in public and may be uncomfortable with too much physical contact. Do not ignore queues or try to jump the line. Czechs are very orderly and respect the concept of "first come, first served". Avoid making jokes about Czech beer. Beer is a source of national pride in the Czech Republic, and any negative comments or jokes about it may not be well received. Do not refuse when offered a drink. It's considered rude to turn down a drink, especially when it's offered as a gesture of hospitality. Remember to take off your shoes when entering someone's home. It's customary in the Czech Republic to remove your shoes at the door," remarked another expat in Zlin, Czechia.
