Sorry, I thought of this while troubleshooting a house the other day. I was trying to find a way to explain to a customer the risk probability of "leaving things the way they are and fixing them when they go bad" type of thinking... you know, the "If it ain't broke, don't fix it" mentality.
Of course, what was I thinking... I don't want or need the work, couldn't find the problem, rigged the gas furnace so that it would work and told her to call another electrician. One of those "it'd be easier if you bulldoze it to the ground and start over" type jobs... Lot's of DIY work, falsely grounded receptacles, twist-n-tape splices, etc.
She asked if it was safe, which started me on the tangent...
