What might happen if a clerk entered a larger amount on a customer's bill than the customer owed?

If a clerk entered a larger amount on a customer's bill than the customer owed, it could lead to overcharging, resulting in the customer paying more than necessary. This may cause frustration and distrust, potentially damaging the business's reputation. The customer might request a refund, which could require additional administrative work and time to rectify the error. Additionally, if not addressed promptly, it could lead to financial discrepancies in the business's accounting records.
