Extra mileage service, polite help without complaining

What a service i received from Lindiwe Ngubane. This woman went extra mileage and help me. I went to Checkers hypers mall of Africa, and the product I wanted was not on the shelve which i asked 2 staff ladies and told me if is not on the shelve there is nothing they can do. Then I went to customer service where i meet Lindiwe Ngubane which she went to the shelve and remove the bar code and checked in her computer if there is stock, less than 2 minutes she said to me it shows there is 39 in stock, then she called a gentleman to go and get them from the back, I was so moved by her service, polite and going extra mileage just to help a customer.
