One thing that irritates me is when little kids want to "dance" to the latest fad dance because their parents think everyone wants to see how precious they are. I sometimes have to accommodate them, if the party is spending hundreds on dinner and they are leaving big tips. I just play the song from Youtube and let 'em dance. Just one per set though, so it doesn't bother the other people.
It's all part of playing the game, but you always must use good judgement!
