The economic aspects of Sesame Street are often not discussed on the show, perhaps being too advanced a concept for the show's target audience or irrelevant to the series. Topics of the characters' income or paying rent are not addressed. Frequently as well, payment for the goods and services of Hooper's Store and the Fix-It Shop are not shown, leaving many to wonder how the businesses sustain themselves. For example in episode 4142, Alan places an order of bananas to the store. Not only is he not shown paying for the delivery services, the stock is quickly depleted by customers, who do not pay for them as they leave.
