When I took the movie back to the store, the woman told me the fee: $40! I felt so stupid. Later, that got me thinking. Blockbuster made most of its margin from late fees. If your business model depends on inducing feelings of stupidity in your customer base, you can hardly expect to build much loyalty. Was there another model to provide the pleasure of watching movies in your own living room without inflicting the pain of paying a lot when you forgot to return them?
