What's the worst job you ever had?

I used to work as bar/waiting staff in a hotel, it was long, hard, exhausting hours and you literally didn't get to sit down more than the odd minute here and there. We'd end up leaning on walls when we could to try to get some rest! It was shit pay, we weren't allowed tips and the manager was a bully. He used to take great delight in tearing us apart in front of other people. Customers would often speak to you like a piece of shit and you just had to take it.

The only plus was some really nice colleagues.
