An online merchant would be a classical example.

After the order is completed and items are ready to ship, the merchant
obtains a tracking number from the carrier and sends it back to the
customer. The cusomter then uses the carrier's Web site to track the
package.

Let's say your package is on that unfortunate FedEx truck and is now
scattered all over the interstate. Would you try to resolve the situation
with the merchant, or the carrier? Would you consider never buying products
from that merchant again, or would you consider insuring all products
shipped by that carrier?

The choreography by itself does not represent a chain of responsiblity. The
merchant might offer protection against items lost in transit, or maybe your
credit card offers that form of protection. But the choreography does
illustrate the proper interaction that is dervied from such a chain of
responsibilities.
