This example provides a simple choreography where a buyer interacts with a store to buy an item. The store checks the buyer's credit before instructing a logistics organization to deliver the item. In the process of carrying out this business transaction, the credit agency may return a fault if the customer is not known, or the store reject the purchase request if the credit rating is too low.
