I was treated very rudely by the two clerks at the store on March 11, 2013 around 5 p.m. I had a discount coupon that they would not help me with. I had the transaction started on the PIN pad, but they would not assist me with what I had to do next, so I requested they clear my credit card information out of the machine. They acted like they couldn't do anything. I was told that I should hit the red X button, but nothing changed on the PIN pad screen. Neither clerk would directly state that they were not a participating station, yet they would not help me to complete my transaction. This is not the first time I have been treated rudely there. I won't trouble them with my business again. They get zero stars from me...one star shows up here because I couldn't choose zero as an option to submit this review.
