The staff is clever. They make weird rules on the spot. Once I went to drink coffee. I had some beans in my account so I decided to use the 107 beans and the coffee was worth about Rs.130. I showed the QR code to pay through beans. But, without even telling me the cashier deducted just 50 beans and I had to pay the rest of the money in cash. He said the system isn’t using more than 50 beans.
