You gotta love peoples "car knowledge"

Just yesterday, I went into an Autozone for a vacuum T for my truck. The "Help" section keeps shrinking to make room for more gaudy crap to jazz up the Civic. Against my better judgment, I asked the kid behind the counter if they had any vacuum T's. He went to his computer and said, "For what car?"
I couldn't take it anymore, so I said, "Any car. All cars," and left. I ended up scavenging the T from my windshield washer.
