While I agree with your general point I have to disagree the particulars here.

The ground crew did not refuel the plane, because the pilots did not request refuelling. There was no-one "forgetting" to refuel, least of all the ground crew.

The pilots did not request fuel because they thought they have enough. And they thought they have enough because they made a unit conversion error in their calculations. (there are even more layers and twists and turns to this cheese lasagne, but no one "forgot" to refuel that is for sure.)
