Best way! Still my all time best agency driver story is a guy who was driving at jewson as a temp in a class 2 Daf 65 flat bed with a eaton 8 speed gearbox.
He kept defecting it for a funny noise we would take it out no noise.
So he brings it in to go out with one of us so he can point out the noise lol
Round the ring road he go's with one of are guys driving when they get back in the yard after hearing no noise he says to are guy do you always use that little lever on the gear stick lol. The twat was only using the top 4 gears no wonder it was making a noise!
