This gas station does not even deserve one single star. The staff are incompetent. I purchased this award card online to have 5cents off every liter. They are never able to pass it. I went to many others Esso and they all were able to use it and did not even need more than 5 seconds to press a button then scan my card. Everytime they tell me my card is not valid and its a promotion that cannot be applied...then why does it work at other Essos???
