(5)Explain why a bank teller, nurse, or flight attendant must have service mana

Service-providers need technical/operations skills plus human interaction and marketing skills.  A bank teller, for example, must be able to complete many types of financial transactions and operate the computer and associated software.  The teller must also interact with the customer in a pleasant way and market other financial services (cross-sell, up sell, etc.). A factory worker can focus on technical/operations/production skills since they have no or little interaction with customers.   The training for service-providers is more interdisciplinary compared to factory employees.
