Reflection of interview

The topic of my group is Aging Population. We interviewed the people who lived in Yau Ma Tei. First we interviewed the manager of Mc Donalds. As they were working, they were busy. There answer were short. I went to a model shop in Yau Ma Tei with my father before the day I went for interview. I asked for the permission of interviewing who work in the model shop because that person was my father's friend. He worked in Yau Ma Tei for 40 years. He gave us complete answers. Also he gave us the background information of Yau Ma Tei such as the facilities of Yau Ma Tei 40 years ago. He gave us a lot of information. At last, we went to Yue Wah Chinese Product. We would like to ask the sales for information. The sales said there need to work so they refused us. At last, we walked through each levels and observe the people who went to the shop. From the whole process, we got most of our information in the model shop. We got less in Mc Donald's and Yue Wah Chinese Product. For next time, when we need to do interview again, we must ask for their permission first. And then ask for the time they are free. So we won't disturb their business.
