Parts store dummies are nothing new.
Back around 1990 or so I had an Opel GT. Fun driving car, but what a piece of crap! Anyway, I needed something simple like points or something, can't remember, but went to a parts store and asked for this whatever part for an Opel GT. So the guy (young, of course) looks in the parts book for maybe 30 seconds and said, "we don't have a listing for that." Now, I could maybe understand not having the part in stock, but I knew his parts book would have a listing for it. So I looked at what he was looking at, and he was looking at Buick. I told him to look under Opel. So he started arguing with me - they were sold at Buick dealers, etc. So I say well, just look under Opel. He would not do so. Finally I had had enough and walked around behind the counter, went to his parts book and looked up Opel. The book not only had a listing for the part I needed, but the parts store had it in stock.
Another time, not too many years later, I went to a parts store and asked for a set of spark plugs for my 49 Dodge. "49 Dodge!" he said, "I know we don't have anything for a car that old!" So I said, well, just look it up. He tried, said well our listings don't go back that far. I said look in the antique section. He argued with me, wouldn't even look for an antique section. Same as with the Opel, I went around the counter to the parts book (and he knew better than try to stop me), looked in the back part for listings for antique cars, found the listing for 49 Dodge spark plugs and, again, they not only had a listing in the book for them, but had a set in stock.
I just don't bother with local auto parts stores anymore. I can find whatever I need online. And I can do that anytime day or night.
