I fueled at the Pilot (former Flying J) in St. George, UT on 4/18 and used the truck lane because my last Flying J directory indicated they did not have an RV island. I took my Flying J card and Visa card to the clerk inside to initiate the transaction. After filling, I went in to get my receipt and found no discount and that I was charged the credit price. The first stupid clerk said I needed to register my card. The senior clerk gave me the 3-cent discount, but stated that the credit price was charged at both auto and truck pumps, even with the RV "loyalty" card. I won't be loyal much longer.
