What is the necessary I.Q. to understand that you must let people get out of the train or subway train before attempting to enter?
The faster people get out, the faster people get in! SIMPLE!!!
I mean, I am not even from the city, but I was only 5 years old when first used the subway, and I only needed 2.6 seconds to realize that! And I see most grown-up people from the city doing that over and over again!!!!!!
