After your meal, thank your hostess or host, compliment them on the meal, and offer to clean up.

One final word on manners at the table:

Don’t point out someone else’s bad manners.  It is just bad manners.

Now it is your turn.  But I would like to add a little twist.

Have an extremely rude dinner party.  See how many rules you can break.  Keep track and see if you can break them all.  Have a great time.
