Rhino ESB Starbucks Example - Customer no receiving messages

[aa]

Hello

I am trying the Rhino ESB Starbucks Example.

For some reason the Customer is not receving any messages. I turned on
logging for all three endpoints, I can see that the customer sends the
addSubscription Messages to both the Barista and Cashier.

The messages go like this on the logs:

Customer--> AddInstanceSubscription to Cashier,
AddInstanceSubscription to Barista, Sends New Order Message

Cashier--> New Order Message Arrives, Sends Prepare Drink Message,
Sends Payment Due Message, Message Processing Complete Message

Barista --> Ready to Work Message, AddSubscription to Cashier,
AddSubscription to Cashier, Prepare Drink Message Arrives, Message
Processing Complete Message, Ready to Work Message

The customer never receives the Payment Due Message, thus it never
pays, eventually I get the Timeout Exception after the 30 seconds
expire on CustomerController.

Am I missing something here?

Thanks in advance
Regards
Albert
