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

"In Thun, it's important to respect the local customs and traditions. Avoid speaking loudly in public places, as the Swiss value their peace and quiet. It's also considered rude to interrupt someone while they're speaking, so always wait your turn in conversations. When dining, remember to keep your hands on the table (but not your elbows), and always use utensils, even when eating fruit. It's also customary to say "en Guete" before starting to eat, which means "enjoy your meal". Punctuality is highly valued in Switzerland, so always be on time for appointments or social gatherings. If you're invited to someone's home, bring a small gift such as flowers or chocolates, but avoid giving chrysanthemums or red roses as they have certain connotations in Swiss culture. In terms of dress code, the Swiss tend to dress conservatively and neatly, so avoid wearing flashy or overly casual clothes. Lastly, while the Swiss are multilingual, making an effort to speak the local language (German in Thun) is always appreciated. However, avoid using informal language or slang until you're familiar with the person you're speaking to," remarked another expat who made the move to Thun, Switzerland.
