-Imagine a company of theatrical players who go out to various events performing plays. Typically, a customer will request a few plays and the company charges 
-them based on the size of the audience and the kind of play they perform. There are currently two kinds of plays that the company performs: tragedies and comedies. As well as providing a bill for the performance, the company gives its customers “volume credits” which they can use for discounts on future performances—think of it as a customer loyalty mechanism.
