I recently purchased gas at this station and I used discount points from Giant.
They short changed me $33. I complained to the store owner, Balil Khan, who pleaded ignorance. After this I went to Giant and asked them if they had previously had any problems with this store and they said there is a pattern of people being shortchanged on their gas points by this gas station. I hope you can put he word out to be cautious of this gas station or simply avoid it all together.
