In the co-creation of value by firms and their customers, interactions serve as an important foundation for ongoing value-in-use. This study aims first, to explore customers’ positive and negative experiences of interactions with frontline employees; and second, to interpret the findings using service logic. Responses to open-ended questions were collected via mail survey from two types of call centre customers, end consumers of insurance (n=289) and business customers of a bank (n=325). Both types of customers
demonstrated similar concerns but a different emphasis. End consumers were preoccupied with value co-creation during the interaction, while business customers focused more on the outcome, and further value-in-use. The paper interprets the findings using Grönroos’ value creation model, and includes managerial implications.
