All service furnished by the system will be charged for at the established rate to all persons, including employees from departments and agencies of the city, of the transit system or of any other public body; except that this restriction shall not apply to policemen, firemen and transit employees in uniform and in performance of their duties, or to any other group to which it shall be made inapplicable by action of the city council.
