I worked part-time in a department store and a customer came to me demanding a refund for a faulty product. However, the customer had no proof of purchase In this case, it was the store's policy to return the product to the manufacturer. When I explained this to the customer she became very irate. However I could see that it was not personal and I applied the training I had been given i.e. listening to the customer, responding to her concerns and firmly restating the company policy. In this case, as in most cases, this was successful.
Shows a good understanding of how important it is to understand that the issue was not a personal one. It also shows an understanding of company policy and a confidence in applying it. The answer also demonstrates evidence of staying in the job even though this was a regular occurrence and not a pleasant one.
