Extract Method

Looking at your problem code:

void PrintOwing() 
{
  this.PrintBanner();

  // Print details.
  Console.WriteLine("name: " + this.name);
  Console.WriteLine("amount: " + this.GetOutstanding());
}

Love your course.  Apologies, I'm a newbie, using C#.  Respectfully, wondering why it is named PrintBanner(), which I didn't really understand, instead of calling it PrintDetails()?  Wondering if there is a reason not to refactor again into PrintName() and PrintOutstandingAmount()?  So maybe my question is how far down do you go?  Is there a good reason to stop at a specific point and not go further? Thank you.
