My English is not good as I am 12 Yr old and me and my mom is not happy with the NUH staffs. Only a few staff I've seen is nice and the rest are just rude. The first time we look for someone to ask where to go see the children doctor the staff just rolled her eyes and replied as if she was annoyed at us My mom was really confused. So when we reached the children doctors building we were not told that I needed to go and register as we already had an appointment. After waiting for 30 minutes in front of the staff that was helping other people register she asked me why me and my mother was standing in front of her. How am I. Suppose to know. We asked her and she said we need to go to the small little corner to go get a queue number. I'm really frustrated why my queue number had not even appeared on the screen and my queue number just jumped into the miss queue. When we went to the registration counter again they said they called me a lot of time. I was really angry and the girl told me to go take my height and weight. She did not even tell us where and just walked away. I went to ask where and the girl rolled her eyes at me and told me to go straight. I went straight and sit down. A kind nurse came to ask my mother why I was there and we said we were waiting for our queue number. She said if I had an appointment then I don't need to wait I can just go to 6 floor. My mom and I told the kind nurse that the girl at the registration center did not tell us clearly where we were suppose to go. The kind nurse apologised and told me they were tired. I was like if your tired and you cannot remain professional and your gonna give that kind of attitude and piss people off. DON'T TAKE THE JOB. The girl at the main building kept rolling her eyes at my mom. I wanted to shout at her for disrespecting my mom. Don't think that I am young and I don't know anything. Don't look down on me and my mom. Now I'm sitting here waiting for nothing I guess.
