Devoted to customer service and the principles of exceptional customer services

I'm a philosopher at heart, so as I sat here at my computer "philosophizing", a question came to mind,

"When Are We NOT a Customer?"

We are all consumers.  We eat, so we are a customer of a grocery store.  We drive cars, so we are a customer of a car company.  We wear clothes, so we are a customer of a clothing store. 

And doesn't it seem that most of our time is spent shopping as well?  When we're watching TV, which most Americans spend alot of time doing, subconsciously we're shopping when we watch commercials.  When we're in the store, especially places like Target, we spend quite some time deciding between products because there are so many choices.  And if you're the indecisive type, you're looking at alot of shopping time...

So, when are we not a customer?  I can think of one instance, but let's see if you can figure it out.  I invite your ideas....
