10. The Thai Escalator Problem - Why, when Thais take escalators, do they wait until they get to the top to decide where they're going? Having reached the top, they stand completely still a foot away from where the escalator ends and stand with their fingers in their mouths aimlessly looking around, while other people continue to stack up behind them. Nobody can go anywhere until the folks right at the top of the escalator move. This, of course, has never crossed their minds.
