PVC installs
I always get a kick when I'm getting something at HD and overhear one of the guys working in the department advising someone to use PVC 'cause' they don't have to know how to bend it. Same thing going on here except for the interpretive changes in direction. It's a shame that homeowners take so-much advice from these "experts" (NOT!) without any idea if they really know what they're talking about.
But I recollect that when I first entered my apprenticeship, guys who entered fresh from their stint in the service had the "jargon" down, which led me to erroneously believe they knew what they were doing. One guy in particular ended up knicknamed "angle iron".
