Final answer:
To correct a price discrepancy for Ms. Snow after verifying the sale sign is accurate, the cashier would adjust the price manually at the register without needing to void the transaction or call a manager.
Step-by-step explanation:
When a customer, Ms. Snow, points out that a bottle of shampoo didn't ring up at the correct sale price, after verifying that the sale sign is correct, you would need to adjust the price manually at the register. This involves changing the price of the item during the transaction to the sale price indicated on the sale sign. This is a common task in retail settings and can usually be done through the point of sale (POS) system. It's not typically necessary to void the transaction and re-ring the item or to call a manager for assistance unless the correction exceeds certain limits or requires managerial permissions.
