RM50

Today I went to Carrefour to buy something. Total bill RM60. I paid exact amount and put all my stuffs in the bag that I brought along. Suddenly the cashier told me that I only paid RM10. I was speechless. I don't want to argue with her and told her I want to see CCTV. The cashier said she will count the amount of money of the counter and let me know whether is there any extra. However, after she sent to office to calculate to amount of money and told me the account was tallied. I told the head that i would like to see CCTV. Then she told me that it will take 2 hours to process. I decided to pay RM50 and give them my hp number. Actually I was confused whether did I pay or not. I was mentally and physically tired due to lack of sleep for many days. So to prove that actually I had paid the money, the only way is by looking at the CCTV. After 2.5hours, finally she called me that they found my money. I went to get back my money. She told me next time please look at the cashier whenever doing payment. I was speechless again. Why they blamed me for not being alert during payment? Anyway, I m happy. but not because I got back the money but because I had done something right.
