You all mention how guys are trying to save the company some $ with fuel here and there, etc. And then just today, I hear a CHQ who's at FL280 request to get back down to 220 so he can burn more fuel off on his way to (CLE? I think) his destination. haha. A double standard of sorts, it seems.
First of all, as we can see in this thread not everyone cares about saving fuel. Second, it's possible that he was trying to make sure he would be under max landing weight when he got to his destination.
