It is an extreme and I think rather humorous way of showing exactly what functional fixedness is. To these people the escalator means stand there and wait tell it gets to the top. There is no other way to get to the top than to just stand their. Because they are fixed on the idea that all you can do is stand on the elevator, they are stuck.
The solution seems so simple when we are able to look at it from an observers point of view, but many people do get stuck (perhaps not physically like the two on the escalator are but at least mentally). It maybe not be in this particular circumstance, but in situations that are similar to this. Even though the answer is right there looking them in the face, they are stuck. As you can see even the maintenance man, an expert on elevators is not sure how to get out of his current position. Functional fixedness can and will happen to everyone no matter how experienced they are. Everyone can get to the top. All they simply need to do is walk off the escalator.
