Static grounding on composite panels - why do people keep skipping the right steps?

I was out at a regional hangar last week helping a buddy with a 737 rudder repair, and I watched three different guys skip the bonding strap step on carbon fiber panels. They just slapped the static line on a nearby metal bracket and called it good. But here's the thing - composite panels don't conduct like aluminum skins do, so if you don't ground directly to the panel's embedded copper mesh or the approved grounding stud, you're basically just pretending. I actually had a static spark jump from an ungrounded composite panel to my wrist last year on an A320 empennage job, and that was the moment I realized how many people are cutting corners. It's not just a paperwork thing either, it's a safety issue with fuel vapors and sensitive LRUs nearby. Has anyone else noticed guys skipping the proper grounding points on composites or am I just seeing the worst techs in my area?

Started taping the copper mesh to the bonding strap before I even clamped the panel down (learned that one the hard way after a spark too, scary stuff). Makes it way harder to skip the step when you've already got everything prepped and lined up right.

Dude yeah, I totally do the same thing now after I got zapped by a live panel that I swore was dead. That spark was no joke, felt like someone slapped the whole side of my arm. Now I got a roll of copper mesh and some tape right in my tool bag next to the bonding straps, so I can't even grab the straps without seeing the mesh first. It's honestly the only way I don't forget because once you start peeling that tape off, you're committed lol. My buddy still just clamps first and does it later, I keep telling him he's gonna learn the hard way too. That prep work feels stupid in the moment but it saves you from a real nasty surprise later on.
