My dad would take me out during the school holidays , I had me own suction cup steering wheel, dolly knots at 10 years old and getting sent in to pay the fuel with the opening line " Morning mate " whilst Dad ducked down behind the cab waiting for me to climb back in the drivers side , Good times good laughs, told not to repeat what was said or head out on the road, though the occasional swear word would annoy Mother, but not the pack of white sugar we scored at Shoreham dock during the sugar shortage back in the 70’s !
