Much earlier in my life, I worked for a transport company as a apprentice. Exactly the same - well, almost, but the palette jacks were not motorized. We raced them on the loading dock ramps, one false move and it could be rather serious dropping off the edge of the ramp. Yes, kids ..... I was about 15 or 16. Back in those days school was done after 8 grades and one started a apprenticeship, with 2 half days in trade school per week.
