Had a similar experience with a newbie fire mage half a year ago, helped him improve. But he was also willing to take advice and to practice. I cannot stand people who don't have a clue and don't want to take advice, either. Even worse, if they have no manners.
Though I usually don't react to gold beggars, no matter how polite. I gladly help out with advice how to make money (which is really not hard today because you can sell almost anything in the AH for insane amounts), but I only gift gold to friends and guild mates. I never begged for gold, especially not people who are total strangers to me.
