Things I've done in my time. No particular order.
Waiter (in lots of places, some for extended periods of time)
Barman (ditto, but most memorably in the Chapel, Coggeshall)
Run a video store.
Sold suits in Hoopers, Colchester (did that for three months).
Worked in Argos (Saturday job through Uni)
Programmed databases (dBase IV, again, 3 months).
Cleaned industrial spray-paint booths (two weeks - worst job ever).
Petrol pump attendant (on and off for several years).
Civil Servant (four years).
Customer services dept of Anglian Water (three months).
Financial dept of Anglian Water (two months)
Caretaker (janitor) of primary school (one year).
General building work (on and off through my teens).
Of course, I'm now a priest, full time since '99.
Nothing too exciting, but reasonably diverse. I have certainly met an awful lot of people.
