Not a flex at all dude. Just speaking from experience that when a tech guy says you need something and lets you roll anyway, and then you show up the next time without said thing, it's a huge double middle finger and a loud & clear sign of no respect, and a sure way to fast track yourself onto their shitlist. Take it under consideration or don't. I don't really care what you do. Thought you might appreciate the insight but clearly you don't since you for some reason feel compelled to be a snide ******* about it. (I'm just treating you accordingly, as you say. Don't take it to seriously

)
BTW, straight from NED's racer handbook. Surely you're so familiar with tech inspection that you've already committed this to memory, but I'm listing it here for the rest of us that ain't so learnt-

So yeah, like I said, they've been giving you free passes. It has nothing to do with the seat, though I'm sure they could nail you for the seat itself too since it may not be properly installed per manufacturer's instructions (no rear mount).
