What should be done by the teller in case the cash does not reconcile at the end of the day?

If the cash does not reconcile at the end of the day, the teller should first double-check their cash counts and transaction records for any discrepancies or errors. They should then review the day's transactions to identify any mistakes, such as missed entries or incorrect amounts. If the issue persists, the teller should report the discrepancy to their supervisor or manager for further investigation. Additionally, maintaining a clear and accurate record of all transactions can help resolve the issue more efficiently.
