White van men...
Starting a new job in 2003 at a marine engineers (before the smoking ban came in), I'd been sent on my first day with another mechanic (Liam, if memory serves) to look at a fishing boat 20 miles away. He duly explained to me how everything worked at this firm, and explained also that this particular customer took a particular pride in his boat (smoking was off-limits, and to be very careful not to get the boat dirty with overalls etc). Because we couldn't smoke on the boat, we smoked in the van instead, and one of the first "tricks" he showed me was how to steer using his knees, whilst rolling a cig with wrists atop the steering wheel.....
My usual trick was to roll a load of cigs the night before, which was much easier than trying to do it on the job.
