A superficially boring issue like someone who doesn't know how to fucking google it could be a much more interesting problem. Is your program laid out well? Is there some hitch in the workflow that you're not noticing because you've gotten accustomed to some misfeature? Are they trying to do something with the software that you didn't intend, but could make good money at by offering as a companion product, or other upgrade? These are things that support can teach you, because you're actively engaging with someone who has a problem.
