What was the worst airplane experience you’ve ever had, that was entirely attributable to a fellow passenger?
A friend of ours told a story about one passenger who – after a series of unfortunate incidents in the airplane’s bathroom – ended up not wearing a shirt for the duration of the flight. How would you like to end up sitting next to THAT guy? Oh, there was a logical explanation of how he ended up in that predicament, but did you really want to ask the question in the first place?
