One job even included taking things out of boxes: in this case cutting open tea packets and pouring the tea back into the chests! I also worked on a local building site, mainly making tea, bacon sarnies, fry-ups, sweeping up and helping in the site office. One day though a huge artic arrived full of bricks and it was everybody to help including me and the site agent. This was in the days before cranes so it helped me get nicely toned!
Picking tobacco in Canada paid well too, but in my day we had grants !!, so I didn't bother working in term time. On the post at Christmas, of course..
