We see this kind of thing much too often, huh? Most people never even realize the hazards. For the price of a w/p blank cover, a life could be saved. It's up to us "in the know" to point things like this out to shopkeepers and the like. Most I've talked to seem pretty receptive, others don't care until you say the magic words (law suit, fire hazard, etc.) And I'm not just out drumming up work, I usually refer them to someone. In a way, it's our duty to educate the ignorant public. Oops, I'm lecturing again.
