Just as in other countries, Switzerland has numerous common rules of conduct and manners. Knowing them makes living together with Swiss people much easier.
Punctuality: It is expected that you show up on time for a meeting. This applies equally to the professional world, public authorities and private events. If you notice that you are going to be late, call ahead and let them know.
Encounter: If you walk past someone in a small community, you say hello - even if you don't know the person. In cities, this happens very rarely.
Greeting: In German-speaking Switzerland, people shake hands in greeting. It is considered polite to look your counterpart in the eye. Among friends, people sometimes give each other three kisses on the cheeks (left, right and then left again - or vice versa). But be careful: This does not apply in every case. It is best to find out what is customary in your own region.
Visit: Most Swiss people do not like spontaneous visits to their homes. It is best to call ahead and ask if a visit is wanted now. Before entering the apartment, one inquires whether one should take off the shoes.
Invitation: If you're invited to dinner, it's a popular custom to bring a small gift - such as a bottle of wine, chocolates or flowers. But be careful: Not all flowers are suitable (red roses only for partners, white asters are common at funerals).
At the table: Before you start eating together, you wish each other a good appetite. If wine is drunk, the glass is raised at the beginning. You look each other in the eye, clink glasses and say "Cheers" or "Cheers".
Conversation on the phone: When you call someone, you first greet them and say their name. Only then does the actual conversation begin.
These behaviors can vary significantly by language region or social group. If you are unsure about a situation, it is best to ask. This relaxes the situation and you get to talk to other people.
