Story time, from my past.
Waiting on full flight in Europe, good airport, for take off. Pilot says over speaker : " We are delayed becuase FUEL guy got UPSET on tarmac and has QUIT. We know need someone ELSE to fill the plane with FUEL. " Said in a COMPLETELY nonchalant voice.
Immediately I get concerned, try not to think what cause a FUEL TECH to QUIT regarding THIS PLANE and fuel issue. Just close my eyes, relax.
2 minutes later pilot comes on intercom again "For some WEIRD reason, someone wants to get off the plane. Now we have to wait for ground crew to find his suitcasebecause of rules. How annoying.."
Plane waits for an hour on tarmac for BOTH passenger to get off and for FUEL to be finally "resolved".
Arrive eventually at destination.
Most of the trouble would have been avoided if the pilot had not sounded nonchalant about a "NON ISSUE about FUEL that a technician just QUIT OVER". I swear i even rememebr saying the statement with a hint of humour, like what on earth is the problem.
This is a true story, and the fact this incompetence happened to me, well I wouldnt have believed it otherwise.
I imagine everyone involved know that they are doing dangerous things, not taking a drop more fuel than is legally required for profit, knowing that none of that is going to change unless there is a major accident... They keep[1] landing these planes with X minutes of fuel left, but it doesn't do anything, until some plane falls from the sky with 0 minutes of fuel left then everyone knew all along and the rules are changed and nobody is held accountable.

lacking fuel in plane that has not started flying isn't exactly something that should stress anyone and most definitely non issue
You missed the point of the story, the issue was not lack of fuel, it was a crew member quitting because of a fuel issue, most likely a misunderstanding.
Fuel misunderstandings have resulted in numerous serious incidents, try googling it bro
