Consider these two cases,
Case 1 – You go to a textile shopping mall. One salesman can hang around you every time and try to sell products.
Case 2 – You go to a textile shop. The staff warmly welcome you. But they do not come with you. They give you a chance to select the product. But when you do not have the correct sizes, you go for them. When you ask for the correct sizes, then close more to you.
Case 1 is traditional sales and case 2 is the high ticket closing.
