Mustafa was elected to the post of treasurer for two reasons, firstly he was a mathematician, and secondly he had a reputation for the sort of "creative accountancy" we require. He developed this reputation whilst playing various CCGs and has become known as "the dishonourable Mustafa", whilst he denies this completely it is rumoured that he infact hides cards under his cap whilst playing (I can't think of any other reason for wearing a cap). His skills seem to have carried over to his position as treasurer and he has in fact managed to make a profit from film screenings.
