Unfortunately, to make sure that every eliminated player receives credit for the proper place finished (and the appropriate money), they must wait at their table for up to a minute after busting -- until a runner makes their way with a slip indicating the place. (Floorpeople radio bustouts by table and seat number to the central podium, so the bustout order is correct.)
Most players want to disappear as quickly as possible once they bust, but now they must linger and watch their final opponent stack the chips which were formerly theirs.
