Good for you, take the moral high ground and leaving him be. Lets hope you don't bump into each other later in life at the same studio :p

I might have done the same, but I would have put in a sarcastic comment saying "...thx for the comments, but do you have an Academy Awards Nomination?".

But hey thats me, would have got him to wind in his rather large neck.

Good Luck in the future.
