Several years ago I have done consulting for a large travel booking service that advertises on TV. As strange as it might sound, there's a large artificial delay added between the time the service knows the answer to customer's search and the time the answer is sent to the customer's web browser. The reason for that delay is that the without it the customers do not believe that the service performed an exhaustive search and do not complete the transaction!
