Should the arts come with a money-back guarantee?

On Wednesday, we heard about a theatre company in Chicago that offered patrons refunds to one of its productions. At the end of the performance, an actor would step up on stage and announce the offer - cash refunds for audience members who didn't enjoy the performance. The experiment has divided the theatre community. Some think it's a good way to get an audience to try theatre risk-free. Others think it's an insult to the actors and the rest of the company that worked on the production. Most movie theatres offer refunds. Some musicians have even experimented with it. Is there a place for refunds in the consumption of art? Tell us what you think.
