Valero review: misleading signed on the gas price

8/9/19: at 6.45 am
The gas price board is listed as pay cash: "$3.41" and credit card: "$3.51"
I gave the attendant $40 to get the discount price. But when I went to put my gas the wash price of $3.51 and I went to ask the attendant and he said I have purchase car wash in order to get the discount gas price. There is no where on the signage board saying buying a car wash you get a discount on the gas. This is misleading and fraud. The gas price is sky rocking and here is a gas station trying to con their customers! I was late for work and I did not have time to take pictures.
