I had that experience before too. Guy reminded me of Comic Book Guy from the Simpsons, lol. I was looking for a piston lock tool, and he's like "Well I've never heard of that, and NOBODY is running nitro anymore" (meanwhile there were like 10 nitro trucks sitting on the shelf behind the counter that had been serviced and waiting for pickup, lol). I came in another time, to get glow plugs, and he starts going off on nitro again, saying "Nitro is going away, I personally prefer electric because I just plug it in and go". All in the Comic Guy voice, haha. I told him yeah, I just prime my engine and go, what's the difference? He starts saying, well you gotta tune it, blah blah, nobody wants to deal with that anymore. I told him that usually takes a few seconds if you know what you're doing. He kinda shut up after that, and I don't think he works there anymore.
