Always say "danke" (thank you) for any service or help received. Swiss society appreciates manners.

If invited to someone's home, it's thoughtful to bring a small gift, such as wine, chocolates, or flowers (avoid chrysanthemums or white lilies as they're funeral flowers).

Maintain good posture at the table, use your napkin, and wait for everyone to be served before eating. Chew with your mouth closed and pass dishes politely.

Switzerland has a conservative dress code. Opt for neat, understated, and well-fitting clothes. Even for casual occasions, appearance matters.

Dress modestly when visiting churches or religious sites; cover shoulders and knees.

Wear appropriate swimwear and limit revealing outfits to the beach or poolside areas.

Greet people with a "grüezi" (hello) or "bonjour" and a firm handshake. Farewells are similarly formal with an "auf Wiedersehen" or "au revoir."

Tipping is not obligatory as service charges are included, but rounding up the bill in restaurants is a polite gesture. Tipping in taxis is not expected.

Knowing a few key phrases in German, French, Italian, or Romansh (depending on the region) is appreciated and seen as a sign of respect.
