Underfilling of fuel dispenser.

Underfilling of a fuel dispenser occurs when the dispenser does not dispense the full amount of fuel that the customer has paid for. This can happen due to a malfunction in the dispenser, inaccurate calibration, or human error.

Underfilling can result in customers not receiving the full value of their purchase, leading to dissatisfaction and potential loss of business for the fuel station. It can also lead to legal issues if customers feel they have been cheated and decide to take action against the fuel station.

To prevent underfilling, fuel stations should regularly calibrate their dispensers, train their staff on proper usage, and conduct regular maintenance checks to ensure accurate dispensing of fuel. Customers should also be vigilant and report any discrepancies in the amount of fuel dispensed to the station management.
