What was he doing exactly in the bathroom? What was there previously?
I am picturing a switch with its own "single gang" cover plate, then another switch with another single gang cover plate, etc??? Do you have photos you can post?
Then what was he doing with the "utility light"? Was he installing a light up high on a utility pole outside? Pictures?
Also was he told to keep the costs down by any chance? What was said to him before he did this work?
