Handpainted seat numbers and safety notices in the cabin? Need I say anymore?

Well, there is the inedible food, hostile F/A's and minimal pitch. Back in the days when I was a grotty backpacker I used them CCU - DAC - KTM. It was an experience, especially landing at KTM in a DC-10. We braked so hard on landing I though we would end up on on the nose. Very, very disturbing.
