A travel expense advance shall be considered as having been made to a city official or employee to be expended as an agent of the City and for the City’s purposes only, and specifically to defray necessary costs in the performance of official duties. No such advance shall be considered as a personal loan to such official or employee and any expenditure thereof, other than for official business purposes, shall be considered a misappropriation of public funds. (Ord. 685 § 6, 1975).
