bad service @ one of the stall @ PJ 19 food planet

due to the rain, me & my hubby went to the neighbourhood food court that has a shelter car park for dinner. i had ordered a 'kum heong pork rice' from this 'specia rice stall'. while my food being served, my hubby paid the staff RM10, the cost of the food is only RM6. So, of course we were waiting for the balance of money to give us back. When I was about to finish the rice, my hubby asked me whether we have receive back the change. I told him no. Usually it will not take a such a long time for them to give you back your change. Once done with dinner, i waited for a while more. I saw the staff served food to others and she din't stop by at my table. So while my hubby still eating his noodles, I walked to the stall to ask for my change.

I approached the chef @ boss of the stall. I told him the situation. Then he asked the staff and the staff told him that she had given me back the balance. I was shocked! At that time, there were 2 customers trying to figure what to order from the stall. So the chef @ boss told me he is just in change of cooking, the rest of the matter he doesn't know. And the staff insisted that she has pay me back. I then asked when, where & how much? Then she wasn't able to asnwer me back. I told the boss i paid RM10 and the food only cost RM6, and I don't have my balance back. The boss asked me to ask other people. I was like "what?, why do I need to ask other people while I order the food from your stall and your staff served me the food & took my money!" I think then the boss not happy and don't know how to deal with the situation, he then at the very unfriendly tone & gesture, he said "kasih dia balik duit!". He repeated twice to the staff. After I got my money and i walked away with a furious mood. And i swear that I will not order the food from him anymore!
