I found out while looking at my receipt. I was charged the cash price. The receipt did show I paid the cash price "but" was not given the extra .06 off. I had to go into the cashier and explain it to them. The only way to be sure of what you paid is to look at the price you paid at the pump. Even if I have to go into the fuel desk,I never leave without my receipt for my records. I swipe my card at the pump, fill up and get my receipt and look at what I was charged. An example of one of my fuel stops: credit card was 3.89 and cash was 3.83. My receipt showed I paid the 3.83 when I should have paid 3.77. This was not just the only one. I fueled 7 times and had the same problem at them all.
