I once spent a week in an army jail in canada, the guards made my life very uncomfortable, (as expected) but seemed to take great personal satisfaction at my discomfort, especially on my release day, when it was "do this, then you can go, do that then you can go" etc. The last thing the pair of idiots asked me to do was make them a cup of tea, so I dutifully filled the kettle up with my urine and watched them drink it with big smiles on their faces. I was like a child.
