(2) refund. If the voyage is less than the number of the current refund the original number of votes equal to the passengers, the passengers in the corresponding table to find the passenger, the changes to the voyage and the passengers on the data table. When as a result of a refund, making the passenger booking the number of zero, the table to withdraw from the passengers of the passenger Otherwise, the corresponding message.
