How funny is this!

In Miami Airport my fellow passengers and I were making our way towards immigration and had to go up an escalator. I was just about to step on when suddenly it stopped. The 20 or so Americans on the escalator just looked around with a 'what do we now look on their face' and, I kid you not, waited - not knowing what to do. They were helpless! It took about 7 seconds before someone figured out 'Hey, it's okay. We can use our legs. They're stairs!' Crisis averted....phew!
