I understand what Kishore is talking about. I have experienced, the "push" in a local city bus, while trying to get out, many times in Hyderabad, India. We miss the station, if we are not strong enough. I believe its probably because, there will only be few seats compared to the number of people who need to get in, those who get in late will end up standing in the bus.
Its almost a decade since I have been on a city bus in India, but thinking back about it, I feel it is okay. If you are strong enough you get to push back or push out, or like in another thread, tell your neighbor (read: tenant) what kind of internet connection they can have. Life is very fair, but only, as long as you are strong enough to keep it that way.
