What should a teller do if they encounter a discrepancy during a transaction?

When a teller encounters a discrepancy during a transaction, the appropriate action is to notify a supervisor immediately. This approach is crucial for several reasons. First, discrepancies can indicate potential errors, whether from the customer, the teller, or the system, and addressing these issues promptly can help prevent financial losses or fraud. A supervisor is better equipped to handle such situations, as they often have more experience and authority to investigate the discrepancy, reassess the transaction details, and take any necessary corrective actions.

In addition, involving a supervisor helps ensure compliance with the bank's policies and procedures, which are designed to protect both the bank and its customers. Taking immediate action shows professionalism and adherence to best practices in banking operations, which enhances customer trust and satisfaction in the long run.
