Tell me about a time you dealt with a difficult or irate customer. How did you handle it?

Situation

When I was a cashier at a retail store, a customer became very angry because a promo discount was not automatically applied to her bill. She raised her voice and started complaining loudly in front of other customers.

Task

I needed to calm her down, understand the issue, and resolve the billing error without escalating the situation or causing a scene.

Action

I listened carefully without interrupting, maintained a calm tone, and apologized for the confusion. I rechecked her receipt and our promo system, discovered the discount code was not properly tagged, manually corrected the total, and explained the adjustment clearly. I also offered a small store voucher as goodwill for the inconvenience.

Result

The customer's anger turned into relief and gratitude; she thanked me and even left a positive feedback note. My supervisor later commended my composure.
