50 hours in Seoul

As I was completing my first fifty hours in Seoul, I was having the first experience with Seoul underground metro railway. We took a train from City Hall to Euljiro 3 (probably pronounced as Al-gero), shifted track and then took another train to Chungmuro. Then we discovered that our hotel is at 2 minutes walk from Chungmuro railway station. There are a lot of things that can be written about the metro. But I guess it's no different from metro rails in other developed contries. Every Indian knows about them either from his own experience when travelling abroad, or has heard about it from someone who has travelled. So I won't write much about it. I want to write about just one thing, that struck me, and I am not sure whether you'll not find it everywhere.

To come up from the underground railway station on to the road there are escalaters. These escalators are wide enough for two persons standing besides eachother. However on no step there were two persons standing. Everyone was standing on the right side of the escalator. The left side was free for people who were in real hurry and were running up the escalator to save time!! I loved this spirit!
