If we're talking about peaking I'll throw my hat into the ring
I am an airplane mechanic. To do that, you need an FAA liscense, which means you have to go to an FAA school where they teach you literally every concept you'd need to know.
This story takes place in the powerplant series of classes (the classes for the engines, including jet engines and piston engines), specifically powerplant electrical. Our instructor required us to pair up. Given that I was a shy and not terribly confident kid, I wound up being paired with the black guy in the class, who I will call jamal. We were then given a simple task: Go to the system description and wiring diagrams of the electrical power generation system for the Cessna 172 and Boeing 727, learn their components and how they work for an hour, and then point all of that out on the aircraft and explain it. Really simple stuff, the diagram shows you how its laid out, and the system description explains how it all works, in a paragraph or less, at an 11th grade reading level. Now jamal had his nose stuck in his phone, and was several years older than me, so I figured best not to bother him, and id go ahead and work on learning what I needed.
After the hour we were given we went out to the aircraft, the 727 first. I was first on deck, and had no issue. As i said its simple stuff and we had an entire hour to figure it out. Jamal on the other hand, could not name a single component or system until he was given some very leading questions. When we went inside to the 172, the same scenario played out, except this time he was able to name the alternator (presumably because those are on cars too). This baffled me, since it was a super easy project, and we had a ton of time to do it. Jamal wasn't a slow guy either, and i realized he had just sat on his phone watching football the whole time.
In another class (I cannot remember what it was, powerplant instruments maybe?), though the same instructor, we had a paper test to take. Standard procedure applied of course, as we all knew and was dictated to us by our instructor: phones turned off and off the table, laptops closed, smart watches turned off. Well turns out jamal decided that rule did not apply to him, and left his laptop open and on during the test. He was obviously accused of cheating, and sent to the dean of our school. This did not lead to anything as his laptop, as far as we knew, was only on the homescreen, but he sure was mad about it for the entire month following, despite the entire incident having been his fault.
These experiences peaked me. These people put in 0 effort, are immensely lazy, and flat out ignore the rules. They are then failed by that, and just get mad and blame literally everyone and everything else. It always ends up making me a little irritated when i see some "oh no iss just the man keepin us down we work so hard for all we gots and it just ain't enough" when i know they're just lazy and unreliable, or even worse, when its one getting some scholarship that i know they didn't earn and definitely will be wasted on them.
