Sometimes it depends on the part. Most times it depends on the service. I can go to Advance in Morganton and ask most of the guys to "step away from the computer" and go find what I need. Orielys in Drexel are a good group of guys too and allowed me to do the same thing. They are just the furtherest away from me. NAPA in Morganton is OK, and have some things the others don't, like Spicer joints, but their prices are usually a lot more.
All in all, after buying so many parts I get treated pretty good at all of them except the Zone, but I had issues with them years ago, so I don't get the personal touch there because I don't visit there as often.
