Sure, I understand that he is not an inherently mean person, who went looking for a sloppy code to bash. I meant that if he acted this way once, there's a good chance that he said something similar before, but it went unnoticed at that point.

Given his apology, he clearly would've not made that remark in person, nor would have he done it if didn't have a receptive audience that appreciates such snobbery.
