If you say "yes" to his white chocolate offer, then he will be pleased.
If you say "no" to his white chocolate offer, he will make you wish you had said yes.
What I advise you to do is to bluff and beat him at his own game ( very difficult that one) by saying you will accept the white chocolate with great pleasure, as long as he can guarantee you a "constant" unfailing supply.
hahahahahaha
