I have a friend who works at a large home improvement retailer. He often tells me stories about customers who buy expensive and sophisticated tools, yet have no DIY experience or knowledge on how best to use them.
Often these customers come back a few days later, hoping to return the tools because they “are not working” when in fact, there is nothing wrong with them; they are just not being used properly. One customer, for example, returned an expensive “defective” chainsaw. The problem was that he never bothered to read the manual, which instructed mixing lubricant oil into the petrol. As a consequence the chainsaw’s motor was permanently damaged.
