Worked in a grocery store. Got adept at guestimating weight of cherries. It was matter of pride not to add or take away from a 1/2 pound scoop.
Worked as an industrial cleaner at the building of the Dinorwic Pumped Storage scheme. Saw amazing things like the huge turbine hall before any machinery was installed. Risked death cleaning the rafters of a machine shop with a back pack Hoover, scrabbling around 20 feet above heavy machinery. Discovered just how filthy miners and heavy labourers could be!
As an auxiliary nurse, I can't quite trump the blood and gore stories of an ODO but saw some pretty rough stuff nonetheless.
