I. Introduction
For any service, it is not unusual to have failures. When failures occur, customers usually feel disappointed, uncomfortable, and/or dissatisfied about the service provider. A dissatisfied customer can take actions such as, complaining to the firm, having negative word of mouth, and/or exiting. In these cases, firms face losing both customers and reputation. Naturally, when service fails, a firm should take immediate actions to prevent customers from switching to competitors. Service recovery efforts are such actions.
