Haha!!! Maybe the installer was having a bad day.... then again sheer stupidity comes into it somewhere
Nothing surprises me with builders. The builder who did our PPOR had put the storm water outlet in the middle of our driveway. I had to argue with them and faxed them the council spec which clearly stated 2 meters from either side of the driveway to get them to move it. It was a stupid thing their plumbing contractor had done but they both tried to get away with it. Cheers
