The Swiss are generally quite formal and their customs and etiquette reflect this. When greeting people the custom is to shake hands with everyone in the party. Upon leaving, you are expected to shake hands with everyone once more. Depending upon which linguistic part of Switzerland you are in, you will address people formally as Herr/Frau (German), Monsieur/Madame (French) or Signor/Signora (Italian). Address everyone by their surname, unless invited to do otherwise, and avoid asking any personal questions, for example, someone’s age, marital status, occupation, etc. The Swiss are very private and will likewise respect your privacy.
Punctuality is expected, so it is important to be on time to any meetings you have arranged. To be even five minutes late is considered rude. Pointing an index finger to your head is considered an insult.
When at someone’s home for dinner, the host proposes the first toast. Do not take a drink until this has occurred. Hands should be kept on the table during the meal and not in your lap, though be sure to keep your elbows off the table. Salads, potatoes and soft foods are to be cut with the side of your fork, not your knife. Use utensils to eat everything, including fruit, as using one’s hands are considered rude. Try to finish everything on your plate, as it is considered impolite to leave food. When finished eating, your knife and fork should be placed next to one another on the plate at the 5 o’clock position. When dining at someone’s home, it is appropriate to bring a small gift of chocolates or flowers for your host. Avoid roses or carnations, which are considered romantic, or the funereal chrysanthemums and white asters.
Do not chew gum or clean your fingernails in public, and avoid keeping your hands in your pockets when speaking with someone.
