Table manners are Continental -- the fork is held in the left hand and the knife in the right while eating.
If there is a seating plan, you may be directed to a particular seat.
Do not begin eating until the hostess says 'bon appetit'.
If you have not finished eating, cross your knife and fork on your plate with the fork over the knife.
Do not rest your elbows on the table, although your hands should be visible and not in your lap.
Finish everything on your plate.
Do not cut salad with a knife and fork. Fold the lettuce on to your fork.
Peel and slice fruit before eating it.
Leave your wine glass nearly full if you do not want more.
