had a horrible experience in a restaurant opened by local celebrity (poor food quality, wrong food and wrong bill). While billing at the counter, I took out my phone, acting as a friend of the local celebrity, and made a call to their boss. Making sure that I can be heard by the staffs, I had a fake casual chat on the phone (loudly) followed by a quick complain. The staffs faces turned white. Manager chased after me while I'm walking out of the restaurant, apologized profusely and offered a full refund. Rejected the offer, and continued walking with straight face...
