I agree with Jim over the relative importance of the two player's actions. The player who is not counting his cards face down is committing a minor violation that many players forget. If anyone really wants to convince him to do so then a Procedural Penalty
every hand until he gets it right seems suitable - 10% of a top will suffice.
But his partner is spoiling the game for others, and that means one major warning, and then expulsion. I do not care that she is often a playing director, she is demeaning the game.
