Nobody likes working with airplanes
Before you go blaming airline companies for taking advantage of an obvious loophole in the system, just know that not everyone is on board. This person let the public know that the guy who puts fuel into the plane is probably a 19-year-old kid who’d rather be at home and playing vidya than topping off planes.
Now, what does this mean? Probably nothing. We can only assume that the kid is an honest person who wouldn’t intentionally put the lives of hundreds of passengers by intentionally not filling the fuel tank. Even if the guy is having a bad day, we pray they won’t make it bad for hundreds of families.
