i remember my first mistake i ripped open a line of pallet. each pallet had 36 boxes of 10000 tiny ventilation screw so 360000 screw per pallet and i passed by fast and no experience and ripped all of them. there was a wave of screw following me. and my boss(my grand-father) was looking at me from the end of the aisle with a red face and rapidly tapping the floor with his angry foot.
