Yes, I was also disappointed in him, he didnt seem to join in much, was grumpy and went out very early. He always looked a bit seedy before he went in, so him in jungle vest and shorts was not very good on the eye.
I always remember him on a programme where he put up his own money and advised contestants what to buy, his rival dealers played a prank and told them, he didnt know what he was talking about and was dated, the contestants believed them and told this to David and he really blew his top and threw his dummy out of the pram, so I have never been a fan of his since.
