Showing up.  It's always a good thing in the restaurant business.  That's what you do. ( The subsidiary of that being, that's what a waiter is;  you wait.  you stand there.)  And you know, it's a marvelous exercise.  A good training ground.  Go up on a small stage, all at face level, while engaged in a carefully arrayed set of activities that must respond to a flow, and talk to people.  Entertain.  Advise.  Serve.  Listen.  Enjoy.
