I rarely use my table manners, because I sit at behind my own desk most of the time. :P

My father and brother, both, don't use just ... general manners though. =/ When I'm being forced out going out with them I usually have to talk to the person or whoever they're talking to just so I can clarify what they want and add a couple of 'pleases' and 'thanks's in there. It's really embarrassing.
