Generally speaking without sales, no business exists. Everyone can grasps this concept but why is it that the walls between sales and other parts of an organization exist? Take it one step further – without customers sales are not possible. Then why is the customer the enemy of the business? Too often employees complain about the very people that pay their income. Before the next time you want to tell the customer just what you think of them, remember they pay your rent, mortgage and put food on your table. The customer may not always be right but they are definitely still the customer.
