We(My famlily) have a rib restaurant. I was upset and absurd yesterday. We had a group of people from Kang-Won-Do. Beacause our parents came form Kang-Won-Do, we enjoyed with them and did our best as long as we do. Dissimilarly the other group, we provided many foods such as a buffet. However they complained with an instense feeling, saying that the price is very very expensive. In fact, the cost of provided foods for this group is never expensive. Because it costs a half than the other. I can’t understand saying them. Since we sold food, we haven’t experienced thoughtless things like yesterday. My parents was hurted. So did I. Somehow, I recognized there is a shameless person in the world.
