Too much UI blocking in Customer Application

[mhotan]

• No progress dialog or notification shows up after User initiates checks in. They should be blocked until the application makes a resolution whether the check in request passed or failed.
• After placing an order the user has no idea if the order went through. Easiest solution is the application needs to wait until a response is sent or times out and deletes an order. Or possible solution is to user sendCallback.
• After paying the bill the user should be sent back to restaurant selection. Users were confused on what to do after paying the bill.
