Travelling by subway can be quite a adventure, especially during rush hours. You have to fight your way into the carriage, and that’s not the end. You also have to protect yourself from big backpacks and fight for space with this who sit and stretch their legs.
To deal with this problem, New York City has start a campaign making people take off their backpacks on the subway. The movement is also aiming at male riders who like spreading their legs to take up two, or even three seats.
Some people say that the campaign limit everyone’s freedom. Male travelers even feel it is unfair, saying that women who cross their legs also take up too much space. So the campaign has been supported by people who are concerned about person behavior in public spaces.
In fact, all countries have written or unwritten rule that travelers are expected to follow. For example, eating and drinking on the subway are banned in many cities, include Washington DC in the US and Brussels in Belgium.
So next time when you take public transportation, avoid bad behavior.
