Discuss the importance of customer service.

According to John Tschohl, customer service is part of successful selling because satisfied customers come back to be customers again. The cost of finding new customers is considerably greater than the cost of keeping the existing ones. There is always the risk that a disgruntled customer might tell others and thus cutting off future customers. Improving customer service skills also helps in a person's self-development. Finally, customer service skills can be transferred to almost any other profession or occupation.
