I tire of construction details!

Just finished levelling the dimmers in the bathroom. I think the box was moved when the drywall was placed on it and shifted. I did the electrical work and I placed the boxes in the same location as they were before but it seems that was about half an inch too far back. The drywall guys simply cut out the spaces and happily spackled and patched looking at light switched recessed half an inch in the wall. Supposedly one of them has been doing this for 15 years. Wow. Fifteen years of screwing people over because of lack of attention to detail. Go figure.
