Has anyone ever had an experience that someone is blocking your way when you are trying to get off from the escalator? After I have started my university life in SFU Surrey for more than one month, I found that there are parts of the students like to stay and think about which direction they should go at the end of the escalator. This behavior is actually very disturbing to others, especially for the other students who are trying to get to their classes on time. Certainly, if there are many students using the escalator at that time, it is possible that everyone will bump on each other and eventually it causes an accident. Therefore, I highly encourage all students that please stay away from the end of the escalator.

In order to overcome this issue, I wonder should there be a “No Soliciting” sign at the end of the escalator?
