<p>I'm not a huge stickler for table manners but there are a few that get to me.</p>
<p>-As others have already said, chewing/talking with food in your mouth (although I'll admit that I'm guilty of this sometimes - it's awkward when someone asks you a question when your mouth's full, and it's taking forever to chew, and you don't want to make them wait forever).
-I'm OK with elbows on the table, but it's disgusting when people have their arms on the table, curved around their plates, and they're hunched over their food. It's like they're trying to guard their food or something, lol. Who do they think is going to come along and try to steal their food?
-Burping and making no attempt to cover it up.
-Reaching across other people for something instead of asking for it to be passed to them.
-(More an issue at home than at dining halls) - You ask for something to be passed to you, and the person passing it to you takes the last bit of whatever it was and then hands the container to you. :P</p>
