Yeah, this grinds my gears. I use to comment my code when I'm working on my personal projects, then at the office I have to waste time trying to decipher my boss's code because he won't comment absolutely anything.
That plus the ridiculous deadlines means that I don't have time to comment my own code, fast forward several months later without working on a particular project and now I have to decipher his and my own code.
One day he actually had the nerve to say to me: 'Yeah, you should comment your code'. How I refrained of commiting murder that day I don't know.
