At one time in my life, I thought I had a handle on the meaning of the word
"service." "The act of doing things for other people."  Then I heard these terms:

Internal Revenue Service
Postal Service
Telephone Service
Civil Service
City/County Public Service
Customer Service
Service Stations

And I became confused about the word "service." This is not what I thought "service" meant.
Then today, I overheard two farmers talking and one said he had hired a bull to "service" a few of his cows. BAM! It all came into perspective. Now I understand what all those "service" agencies are doing to us.
