It's all very well to run down the DIYer, but when a guy that should know better
does a thing like this, it gives Electricians in general a bad name and personally I wouldn't like to be tarred with that brush.
If I saw something like that occur here, I'd institute a complaint to the Electrical Workers Registration Board.
Leaving exposed joints in walls, is just something you don't
BTW, that gibbing work looks nice and neat!.
