Service - Hmm??

I became confused when I heard these terms which reference the word
> 'service':
>
> Internal Revenue 'Service'
> U.S. Postal 'Service'
> Telephone 'Service'
> T.V. 'Service'
> Civil 'Service'
> City & County Public 'Service'
> Customer 'Service'
>
> Thinking about what they do, and how they do it, 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 perspective. I now understand what all those 'service'
> agencies are doing to us.
