Cleaning Tar tankers, big artic lorry tankers with stainless steel clad tanks on the back. When they were being filled there would be spillages and at the end of the week we'd have to clean them and generally make them look presentable. We had to put a solvent on to disolve the tar, then steam clean, soap and water, steam clean, rinse and repeat. The tar factory stank and there were various lagoons of sulphur rich effluent everywhere and you were invariably wet through for most of the day it was pretty crappy but was probably the best paid Saturday job in Scunthorpe at the time. We also worked year round Saturdays and sundays in all weathers. My mate and I were only 17 at the time and just passed our driving tests.
We used to have to rely on fitters bringing down tankers from the workshops to the wash bay to keep us in work because they were the only other people working weekends, but invariably the lazy sods wouldn't answer the phone when we'd ring to say that we were ready for another lorry. This would mean a half mile trudge through the plant to go and tell them.
I decided in my infinite wisdom and thinking on my feet attitude decided "how difficult can it be to drive a lorry" and proceeded to drive a 40ft tanker through the plant, past silos full of all sorts of flamable, toxic and explosive liquids, back to the workshops. The fitters didn't make owt of it however I was filmed on CCTV and after one of them must have told the management,I was promptly dismissed.
What made it worse was that about six months later, I started dating a lovely girl and all was going swimmingly until couple of weeks in, it came to meet the parents time, and I was greeted at the door by the plant manager who'd sacked me! The relationship faltered not long after that.
