When I bought my first Snap On box (5 draw top box) it was in the 3rd year of my apprenticeship, the shop floor guys thought I was mental. The form back then was a cantilever box that you carried from car to car, of course lugging this monster about was impossible. They also laughed every Friday for months as I handed over a chunk of my wages to the Snap On Man!
So I cleared an area at the end of the garage near a bench and moved the cars to me instead. I actually believe I invented the ‘service bay’ ;-). Then I found an old steel small bench on castors at a scrapyard that they sold me for £2. I was now a mobile mechanic.
It took me 40 years to buy a Snap On Roll Cab with draw deviders (thank you EBay) and I have several sets of plastic spanner organisers. When I started doing kingpins many owners wanted to wait and get involved so instead of the constant not that draw the next one, no the other long one, no the one with a kink.... I labelled all draws and containers with Dynatape, then my nuts and bolts racks were all labelled by thread type/size/length.
Happy days as I could sit there and ask for two 5/16” Nylocs.... and all my kit went back in the correct draw after cleaning. (As several on here can testify

)
