Over the last several decades, people have changed. Just as we used to go to a butcher for meat a produce stand for produce, etc., we now seem to want one stop shopping. Like some of my customers, I suspect yours will ask anything, just in case you will answer it for free. This type of thing is one of the reason I had to drop phone support several years back.
Literally, today, I helped someone discover who was using different software, that they were making a typing error. The initial contact was a complaint that the "IRS" was coming up with a different figure than Medlin (it was neither the IRS or Medlin). I get asked for things like if I can make data from X software work with mine, and often, basic computer operating questions. It is a real art to deflect, and keep things within the scope of what they have paid for.
