I've seen a lot worse, even by "Masters". One of my "Dead Giveaways" about DIY's is that the Expurt Lectric Design Services available at Lowes and Home Despot never know about reduced neutrals, the use of which I consider as a sign that the installer had some sort of clue. Of course, that would slightly reduce sales of copper for the big boxes. The clerks in Supply houses aren't hip to the reduced neutral idea either.
