You tell them....then you ask them

Thinking of Jobs': You don't ask people what they want.  You tell them what they want. 

why do we ask people what they want then?  I think you say, "This is what you want"....then you ask "do you need anything else"  ..... you don't start out by asking them what they want. You provide something and then you move to that step.  This seems to be paramount.  And is not necessarily done very often.
