I would put zero star if possible. The sales guy was extremely rude and unreasonable. There's no paper in the card machine and the sales guy said Its my fault. I was with friends and there are other people there who could prove and I didn't even know how to open those machines. I was going to call the police since he's so rude and offensive. He gave me the machine and left to do other things. And then he came back and blamed me that I didn't pay EVEN though the machine itself said duplication payment. It made feel like it's a tricky fraud. And also I paid TWICE for this ice cream. And he kept saying I took his paper. If so, why would I pay twice?!!!!!!!! I've never saw a customer service like this in any country of my life. I would definitely report this case. And never recommend this store to any friends of mine since there's a risk to be scolded and cheated and you probably have to pay twice for that!!!
