You know that guy who submits the 5000-line diffs for review and says "don't worry, it's fine"?
I ran into one of those today at work.
I "returned to queue" five such Christmas Eve diffs from him. I marked each, with increasing directness, with "make this a series of changes that I can understand"
Then it turns out he's gone off on PTO and probably won't be coming back. Gah.
