What a bank cashier should not do?

A bank cashier should not handle cash transactions without verifying the identity of the customer, as this can lead to fraud. They should also avoid discussing confidential customer information in public or unsecured areas, as it breaches privacy protocols. Additionally, cashiers should not bypass established procedures for cash handling and transaction processing, as this can result in errors and financial discrepancies. Lastly, they should refrain from engaging in personal conversations that could distract from their duties or compromise service quality.
