Thanks for the replies. I agree wholehearetdly with the previous poster. I *should* have said something, because she'll just do it time after time.
Me and the SO actually had a wonderful time (delicious food, good drinks, laughter
) before and after her rivetting conversation (what sounded like an arguement with a significant other, she was a alone). But it was really very shocking the way she ignored the comic, well just turned her head away from him and put on her head set.
But you're right, if nothing is ever said to people they will never stop the obnoxious behavior.
