I became confused when I heard the word "Service" used with these agencies: Internal Revenue 'Service' U.S. Postal 'Service' Telephone 'Service' Cable TV 'Service' Civil 'Service' State, City, County & Public 'Service' Customer 'Service' This is not what I thought 'Service' meant. But today, I overheard two farmers talking, and one of them said he had hired a bull to 'Service' a few cows. BAM!!! It all came into focus. Now I understand what all those agencies are doing.
