Why do morons work in auto stores? PLEASE HELP!

[Agent_4573]

So I'm going around today trrying to find parts so i can install everything i have sitting in my garage right now. Well no one has a peice of 2 and 7/8 rubber hose, even the hardware stores. All the auto store only carry rubber hose up to one inch in diameter. None of the autoparts stores carry or even know what a K&N 9 inch conical filter is, and when i asked about spark plugs for nitrous applications i got a "Nitrous, thats cool man! I don't know what plugs are though." I mean if you work in an auto parts store, should you know what spark plugs are? I'm left with adapting the new C&L intake to the 65mm throttle body with electrical tape, and could someone please post a part number and brand of what spark plug they use for nitrous. I'm installing Zex brand 75 shot of nitrous and don't want it to detonate on the first run. Today has made my desicion on the personilized license plate, I'm getting "Ih8PPL".
