Which practice is least likely to help cashiers ensure accurate inventory?

Ignoring customer return requests is least likely to help cashiers ensure accurate inventory because returns directly impact stock levels. When customers return items, failing to process these returns means the inventory count remains incorrect, which can lead to discrepancies in the actual stock available compared to what is recorded in the system. Effective inventory management relies on accurately reflecting both sales and returns, so neglecting this aspect can lead to overstocking or stockouts.

In contrast, regularly updating stock levels, ensuring proper item scanning, and tracking items sold are all key practices that contribute directly to maintaining accurate inventory records. These actions help keep track of what is available, what has been sold, and what needs to be restocked, thus ensuring that the inventory system reflects the reality of the store’s stock.
