Jobs You've Hated

I was listening to a past BTalk podcast this morning while doing some odds and ends at work and they discussing part-time jobs and it made me think of jobs I've had in the past. I've been a waiter, a library worker, stockboy, salesperson, chemist, etc. However, there is only one I truly hated, which I thought I would have loved at the time.

Well, that's my worst job ever. What is yours? :)
