I flew Air India a number of years ago, and was appalled by the filth inside the aircraft. Two hours into the flight, I thought I might use the restroom. Upon opening the door, it looked as though it had literally been turned upside down - there was stuff everywhere, and I couldn't even see the floor due to all the paper towels and toilet tissue that was on it. Talk about mind over matter - I didn't feel the urge to go to the bathroom for the remainder of the flight!!
