If everyone orders relatively evenly, I agree. Trying to itemize in order to equalize a few dollars difference on an expensive meal is lame.
However, there are some people like me who don't drink, and in some cases, don't like the appetizers other people order.
So yeah, if everyone at the table is ordering expensive drinks, and I'm downing water, I'm being the Jew and at least asking for my part to be itemized.
Otherwise I'll be for splitting evenly.
