I don't know about anyone else, but I was offended by the lobster incident. First of all, people don't generally decide whether to keep kosher on a day to day basis - this is a serious commitment. So when Rachel went to sneak a piece of lobster as if she were just cheating on a diet, I was rather upset. Now, the fact that she was eating their food at all hints to a somewhat relaxed attitude about kashruth, but still ...
Second, for George to violate her deeply help religious beliefs by putting lobster in the eggs goes beyond the ususal George-ness into sick sadism. Plus, it answers the question as to whether George is Jewish or not, since no Jew in his/her right mind would do such a thing.
