Terriblle customer service at the Circus!

The service received was awfully bad. At the shop, the man was literally yelling because i did not have cash to pay and he was not in the mood to deal with the card machine was what he said. While giving him my order he gives off this attitude, and slams things on the table, everytime I mention something to be added that he might not have heard me say earlier, he rolls his eyes and does it as if he is being forced to. The staff is not very friendly and helpful. Bad experience.
