My husband and I got our ice cream and at the point of paying, we where advised they could not take our $50 bill, the cashier said it extremely rude. Now..let me add THEY DID NOT HAVE IT POSTED..and took our ice creams back JUST TO THROW THEM AWAY.. wasteful..not like we didn't have enough to pay.. because of their mistake, my ice cream got wasted and I was completely embarrassed. I will never go back there.
