So disappointed. Shopped there regularly since moving to Knoxville and frequently buy gas there. Tried to exchange the lp tank i bought there. Cashier rang up as a tank purchase and had to cancel purchase. Rerang as exchange and card declined. Tried again and declined. I went to the pump and the card worked fine. Checked my phone and my bank requested in store transactions be fraud verified. I verified then asked the clerk to try again. He refused and told me to take my business elsewhere. I offered to show him the message from my bank showing the card was ok to use and he refused to serve me. Very rude. They've lost a customer forever. I was never rude for the record. read more
