Yes.
So company policy at Advance is that any time a customer has a technical question about how to do something on their project you are supposed to use it as an opening to try and sell a Haynes book.
So I had this idiot come in asking me which tool he needs to remove his door panel. I told him I wasn't sure because I wasn't super familiar with the vehicle and had never taken a door panel off one before, and suggested he consult the Haynes manual. None of that was a lie, or out of line for the question asked. He then tells me he knows he needs a push pin tool, he just needs to know which one fits his car. I give him the blankest stare ever, because this has now gone from a somewhat reasonable interaction into "how do you find the gas cap" territory real quick. He keeps pushing me, and I tell him that there is only one. So he flips out, yells at me about not doing my job, and demands to know, based on the information on the back of the package, which pin popper works with his 2007 Yukon. When I tell him, again, that there is really only the one, he demands to speak to my manager, who I knew had been standing behind me the whole time. I stepped aside and just said "Ryan, this guy wants to talk to you". Dude just left.
I had another old bastard who I had a 20 minute conversation with because he was convinced that the NGK spark plugs someone else sold him where going to burn a hole in the piston of his BMW because it was made in Germany and the plugs were made in Japan. When explaining to him that that isn't how that works I even went as far as pointing out that they should work together fine because both countries were on the same side during WWII.
But yes, the number of people who come in not even knowing what vehicle they are there to buy parts for, or guys who have their wives who have no idea what is going on call or come in for parts is truly astounding.
