Issue with the Parts Girl

I was delivering to the NAPA on my route one morning and this customer says "I'll find out" and walks out as I'm coming in and the part guy says "It would help if you new what kinda car you have!". I just started laughing and said what's that all about? The parts guy said the customer walked in and said he thought he needed something (I can't remember what part he was needing) and the parts guy said he didn't even know the make of the truck he had!! He said it was a little red pickup!! I just busted out laughing and the parts guy says "We get all kinds!". This customer was easily in his mid-50s and all I could think was... how did this guy make it this far in life?!?! We still joke about that, I'll come in a say I need a part for a little black sports car
