On the 0ther issue of the lack of knowledge behind the counter. I have an Auto Zone near me where the kid didn't know what points were. On the other hand the guy at my local Napa doesn't even need the computer to find parts for me. I tell (or show) him what I want and he goes directly to the spot and retrives it like he was waiting for me to ask for it. He even sat and figured out all the brake lines and fittings I needed for my truck and made sure I hade everything before I left. If I did it I would have been back at least twice.
A good parts man is a great find.
