All subpoenas issued under the terms of this article may be served by any person aged
eighteen (18) years or older. The fees of witnesses for attendance and travel shall
be the same as the fees of witnesses before the district courts of the state, such
fees to be paid when the witness is excused from further attendance. When a witness
is subpoenaed at the instance of any party other than the manager of finance to any
such proceeding, the manager may require that the cost of service of the subpoena
and the fee of the witness be borne by the party at whose instance the witness is
summoned. In such case, the manager, in the manager's discretion, may require a deposit
to cover the cost of such service and witness fees. A subpoena issued as aforesaid
shall be served in the same manner as a subpoena issued out of a court of record.
