     § 1303.  Adherence to tariffs.        No public utility shall, directly or indirectly, by any     device whatsoever, or in anywise, demand or receive from any     person, corporation, or municipal corporation a greater or less     rate for any service rendered or to be rendered by such public     utility than that specified in the tariffs of such public     utility applicable thereto. The rates specified in such tariffs     shall be the lawful rates of such public utility until changed,     as provided in this part. Any public utility, having more than     one rate applicable to service rendered to a patron, shall,     after notice of service conditions, compute bills under the rate     most advantageous to the patron.
