Showed up to purchase a ticket for a movie. I purchase a seat and soon after, asked to pay for the ticket, which was 19.03 with tax. I pay $20, and after I press Checkout, I get a warning message displaying "Your ticket could not be processed at this time." I don't get my ticket nor my receipt. All I get is .97 worth of change back. I ask Guest Relations for help, and I get told that the seat is still available and wasn't purchased. Staff comes by soon after and decides to check cameras after I explained my situation. I wait about 30 min and I get no help. Staff comes by later on to say to me that they didn't see me pay and payment wasn't registered. So basically, I paid $20 for nothing.
