I received this today: Awesome!  Thanks so much Steve.  After reading most of your book, I did look at my manual and, as you indicated, it says I am due for an oil service on my BMW 330i, so I will go ahead and schedule that with him.  I think what he was trying to sell me was an oil change and a full inspection, which I am not due for.  Wish me luck.
Guess What, the dealership was about to lose a customer.  Now the dealer retained its customer and performed the service. 
She is now an educated consumer.  She saved over $200.   Everybody WINS.
