I'll second that Troopie, just drives me nuts.
Cellphone users is another. You can't talk to some people anymore because they are on the phone while you just sit there. Even if the person you're talking to tries to get off the other won't quit. Either that or they are texting somebody, you might as well not be there.
Why is it that some people think you have nothing better to do than to talk to them on a cell, if you say your busy their feelings get hurt.
Went to a Christmas dinner at my sons GF. There were eight people there but only me, my son and his GF did any talking everybody else was either on a computer or cell. Nobody said anything to anybody most of the evening.
Maybe it's just me but it drives me crazy.
