It was part of the house. May be you are right, it might be more work than he anticipated.
Is this bedroom part of the house that "wasn't there when the house was new"? Otherwise known as a "room addition"?
That would be about the only explanation that would make sense on why he couldn't run a piece of conduit. (or rather, didn't want to...more work. Was this "agreed upon" in price before hand...and then it turned into "more work" than he thought he'd get paid for?)
