Postal clerk Richard Cook, who has barely enough room to turn around in a temporary post office set up on the second level of the ZCMI Center, helps Debbie and Roger Galloway and their daughter Kira, from Fort Lewis, Wash., buy stamps. The tiny post office is one of three temporary offices that will serve shoppers during the Christmas season from 11 a.m. to 7 p.m. Monday through Saturday. The other two offices are in Fashion Place and Valley Fair malls. The three miniature post offices will be in operation until Dec. 21.
