Existentialism Unbound - Sartre's Bad Faith Waiter - Que Sais-Je??

What is one to make of Sartre's treatment of his waiter in one of his famous analyses of bad faith?
The example is supposed to be an obvious one, but the more we examine it, the less obvious it becomes.
Let us remind ourselves of Sartre's example: Let us consider this waiter in the cafe. His movement is quick and forward, a little too precise, a little too rapid.

He comes toward the patrons with a step a little too quick. He bends forward a little too eagerly; his voice, his eyes express an interest a little too solicitous for the order of the customer.
Finally there he returns, trying to imitate in his walk the inflexible stiffness of some kind of automaton while carrying his tray with a recklessness of a tight-rope walker by putting it in a perpetually unstable, perpetually broken equilibrium which he perpetually re-establishes by a light movement of the arm and hand.

What is to be our reaction to the actions of this waiter? The sentences immediately following those I have quoted may mislead us about the answer Sartre would have us give to this question:
All his behaviour seems to us a game.

He applies himself to chaining his movements as if they were mechanisms, the one regulating the other; his gestures and even his voice seem to be mechanisms; he gives himself the quickness and pitiless rapidity of things. He is playing, he is amusing himself.
But what is he playing? We need not watch long before we can explain it: he is playing at being a waiter in a cafe. There is nothing there to surprise us.

If we were to follow the suggestion which seems to be in these lines, Sartre's waiter would be seen as one who could be contrasted with a waiter of a more natural disposition. Some men, while waiting on tables in a cafe, play at being waiters. Others are waiters.

Sartre's description would not need much extending in order to be a depiction of a Uriah Heep-like waiter. Whether we say that he is consciously play-acting or not, we can say that Sartre's waiter is in danger of becoming a caricature of a waiter.
