So true.... just had this happen when buying a VR from our local drugstore... The cashier insisted that I could not pay with a credit card, but said she would try it even though she knew it wouldn't work and pushed a button when I swiped. Then she turned the screen around to prove to me that it did not accept it. I told her I had purchased one from that very location before as well as another location recently and she said she would try it again and it magically went through. I left thinking it was quite interesting that they can even control that when they want to.
