Table manners

Let me tell you something about table manners in Austria and elsewhere.
Indicate you have finished eating by laying your knife and fork parallel on your plate.
Finish everything on your plate.
The host or hostess makes the first toast. Everyone lifts and clinks glasses, looks at the person making the toast and says, "Prost!".

Typical table manners in America:
Don’t start eating until the host tells you, also make sure that everyone have their food on their plates.
Once the meal is completed, place the napkin loosely beside your plate. Make sure you do not crumple or fold it.
Last, but not the least, once you have enjoyed the meal and returned home, make sure you thank the hosts for having invited you.
