What about posture, at home, i spread out i mean legs opened don't give a rats behind, in public keep those things closed lest someone gets the wrong idea. Use a napkin every 5 seconds, keep that mouth nice and clean so you make sure to present yourself properly, keep your napkin folded neatly, if your at a restaurant with linen.
soup and other edible liquids are eaten with a glass or a spoon, cmon.
pizza and sandwhiches, use your hands and some napkins, and a good size plate for those pesky crumbs. (oh, i could go off, but why?)
steaks rice, so forth and so on, knife and fork..... put to lips, open mouth, insert utensil loaded with goodness.
if i'm eating with other people at a buffet, hey try this ok ooh that's good ill get that next time.
at a restaurant a sit down, everybody order something else and we can or can not try each others food, especially if the plates are $25 each or more.
if I go to an expensive place after saving for a month, I spend time, and I mean 5-10 minutes eating an appetizer, dissecting it, eating it all together, dissecting it again.
The world is a stage, and you it's actor.
Enjoy you're meal!
