Except as otherwise provided in this section, no municipal utility shall charge, demand, collect, or receive a greater or lesser or different compensation for any product or commodity furnished or to be furnished, or for any service rendered or to be rendered, than the rates and charges applicable to such product, commodity, or service as specified in its schedules on file and in effect at the time, nor shall any such municipal utility refund or remit, directly or indirectly or in any manner or by any device, any portion of the rates and charges so specified nor extend to any corporation or person any form of contract or agreement or rule or regulation or any facility or privilege except one which is regularly and uniformly extended to all corporations and persons. The governing body of the municipal utility may by rule or order establish such exceptions from the operation of this prohibition as it may consider just and reasonable.
