As consumers, we do not always realize what is the magnitude of the infrastructure required to support the distribution of our everyday purchases.
The various components of these transportation networks must be robust and synchronized in order to perform adequately. This is especially critical in the case of produce (or any other product) with a very short life span.

Talk about high expectations.
