Let us imagine for a moment that you are getting ready to purchase a car. You are going around to different dealers and you arrive at your first stop. You walk into the dealership and a seemingly nice man in a suit approaches you and shakes your hand. You two speak for a moment and you inform him you are looking to purchase a new car. He then leads you to the huge parking lot full of all different models. He takes you to several different cars that are all nice but not one of them has the features you are looking for. You thank the man for his time and return to your old vehicle irritated at the wasted 45 minutes you just spent.
