Service now Defined-from the inbox

I become confused when I hear the word "Service " used with these agencies:

Internal Revenue 'Service'

US Postal 'Service'

Cable TV 'Service'

Civil 'Service'

Federal, State, City, & 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 bought a bull to 'Service' his cows.

BAM !       It all came into focus.     Now I understand what all those agencies are doing to us.
