What are some do s and dont s for table manners?

Don't put your elbows on the table, put your knife and fork together beside each other on your plate when you are finished eating, don't slurp your food, eat slowly, don't hold your utensils like gardening tools, chew with your mouth shut, put your napkin on your lap, take bite size bites.

Also, if you have anything that must be cut with your knife, only cut one bite at a time. Do not engage in stomach turning conversations. Start a conversation about something other than the food in front of you; compliment the cook/hostess about her/his cooking; try not to eat all of anything before starting on another food on your plate.Do not reach for things on the table, but do ask it to be passed to you--even if it is just a weensy bit out of your reach. Do not salt the food before you taste it: the person who did make it might be offended--he/she cooked it to be tasty! Do not leave the table without asking to be excused---but, too, try not to be the last person sitting there. When you have finished, take your napkin, fold it, (no wadding it up) and place it on the table, next to your place setting. If you are female, try to slip your lipstick OFF before the meal: nothing is more icky than to have soiled the napkins with lipstick! If you need to tend to your allergy nose, excuse yourself, without mention of the reason, and sneak away. Same goes for bathroom needs. Smile.
