Service Agencies At one time in my life, I thought I understood the meaning of the word "service." The act of doing things for other people. Then I heard the terms: Internal Revenue Service Postal Service Civil Service Service Stations Customer Service City/County Public Service And I became confused about the word "service." This is not what I thought "service" meant. Then one day, I overheard two farmers talking, and one of them mentioned that he was having a bull service a few of his cows. WHAM!! It all came into perspective! Now I understand what all those "service" agencies are doing to us.
