Wyo. Stat. § 1-14-110
If any officer or other person who is allowed mileage for any services rendered receives at the same time more than one (1) writ or process to serve, or authority to render more than one (1) service at the same place, he is only entitled to mileage for the actual number of miles traveled, allowing a full mile from place to place for every person served or every service rendered during the same journey. His return or claim for mileage shall show the actual number of miles necessarily traveled from the place where he received his authority to the place where the actual service was made or rendered. Should any false statement for mileage be proved, then no mileage shall be allowed for any services performed by virtue of the authority, writ or process by which such services were rendered and the maker of the false statement is liable to criminal process.
