Did part time bar work etc when studying at Uni, but first proper job was driving a van, multi drop deliveries in and around London for an electrical firm supplying building sites with cable/conduit/sockets etc. We'd pick the orders, load the vans and then hit the road. It was actually great fun, some good lads working there and I now know London like the back of my hand, I can get to any part of London by road without looking at a map. I'd probably need one when i get there to find specific streets, but it's a good level of knowledge.
Stayed for about a year then switched jobs, relevant to my degree (Music) to the company I'm at now, have been here 21 years.
