I wish you every success with the business, Peeps and Lucy. Great website - looks like you've got it all covered. I'd certainly be interested if I lived in the UK and had the money!
My wierdest job would have to be at the "pea factory", a summer job when I was a student. Christian Salvesen had a cold storage/freezing plant in Granton in Edinburgh, where they stored and froze various vegetables and fruit, including peas. The picking season was a couple of months during the summer and the peas were picked in the Borders by machine and trucked up to the factory to be frozen, ostensibly within 48 hours. No machine is perfect, least of all one that has to pick peas, and along with the peas, the machines would gather up things like leaves, caterpillars, bits of rabbit, etc, etc. People were needed to remove this debris before the peas were frozen and packaged, so some boffin decided that students would be the ideal breed to perform the task, the idea being that they would be able to sit at the conveyor belt and think about other things while ensuring that your bag of peas only contained the little round vegies.
The job involved sitting at a conveyor belt while the peas and debris rolled along in front of you and picking out all the things that weren't meant to be there. Mind numbing (and finger numbing, as the peas had been washed in something), but well paid - we got award rates and time and a half on Saturday, double time on Sunday.
I have to come clean here, though, and admit that, thanks to my friend, Babs, I only ever did about two hours of conveyor belt time, on my last day of the second year. This is because on the first day they asked for people to help in the canteen, peeling potatoes, making chips and tea mainly. Everybody obviously thought, no thanks, and only a couple of people put their hands up. Babs nudged me and said, "Come on, this'll be much cushier." So I volunteered. Of course, she was right. We got to sit in a nice cosy canteen, serving tea and chips to the students and to the men (the real men that worked there) during the day. They had a cook who made the main meals, and all we had to do was make the tea at the start of the shift (so that it was well and truly black by the time the men had their tea break), cook the chips (apparently I made a bloody good chip), serve up the stew, and if we were on the night shift, peel a dustbin full of potatoes. We were laughing - mainly at the pruney fingers of our fellow workers. Some of the boys were allowed to drive the fork lifts at the beginning, but the union put a stop to that when my then boyfriend drove one into a warehouse door.
I've also been a cook/courier on camping tours in New Zealand, a "supercook" on camping tours in Europe, worked in hotels, in Sandy Caird's shop in Aviemore, and had various boring secretarial jobs.
