Found this list of Swiss table manners via the excellent Swiss Miss blog and think they're useful beyond the borders of Bankerland:
- Be on time.
- Always wait for everybody to be served before beginning to eat.
- All meals are usually started with the words "bon appetit" or "guten Appetit."
- If wine is served, wait until the host begins the toast.
- When toasting, chink your glass with everybody at the table and look each person in the eyes before drinking.
- Keep your wrists on the table, but never your elbows. Do not place your hands in your lap.
- Remember to always say please and thank you.
- French bread is always torn rather than cut with a knife.
- Lift your forearm from the table while moving the fork to your mouth.
- Use your left hand for the fork and the right for your knife and gently push food on your fork.
- If you are served cheese as a wheel, it should be cut from the centre into slices (as you would slice a pie).
- When finished, put your knife and fork parallel to one another on your place as if they were hands on a clock indicating 5:25. If you don't do this, your host will serve you more food.
- Finish everything you take on your plate. The Swiss do not appreciate waste.
Additional children rules: make sure children wash their hands before meals. Children generally must wait to leave the table until everyone is finished.
Good luck with that last one.
