Creative thinking

This morning I go to a shopping centre to buy something. Because of thirst, I intend to buy a canned drink to quench my thirst, I discover a canned drink call " Whatever " the other canned drink call " Anything " . I am wondering what flavour in the drink. To my suprise, we will not know the flavour of the drink until we taste it.
Now, " Whatever " and " anything " already become a brand. I am wondering how the businessman can come out this idea. I believe that he might had observed the surrounding and what people talking. As you know, sometime we can hear some conversation as follows:

A lady to talk to her lover
A lady: Can you do this for me?
Lover: Sure, whatever things you tell me to do, I will do this for you.

A job seeker who was unable to find a job for a long time
Employer: What job can you do?
A job seeker: Whatever job you give me, I will do.

An old man who had no food to eat
A person who had kind heart: Sir, what food you like to eat, I buy for you.
An old man: Anything.

I think the businessman had a creative mindset by observing the surrounding. I think we can learn from this example.
