Final answer:
One technique is offering exceptional customer service and another technique is using the foot-in-the-door technique.
Step-by-step explanation:
One technique for making the customer feel that he or she is number 1 is by offering exceptional customer service. This can include being professional, resourceful, and going above and beyond to meet the customer's needs. By providing excellent service, the customer will feel valued and important.
Another technique is using the foot-in-the-door technique. This involves making a small request or suggesting a smaller purchase to the customer, which they are more likely to agree to. Once they have agreed to the initial request, it becomes easier to make larger requests or suggest bigger purchases. This technique takes advantage of the principle of consistency and our desire to maintain consistency once we have committed to a behavior.
