Sometimes people pull the emergency brake for nothing!

Well I have been there...in the subway with nothing to read, no one to talk to, or no video game, just reading and re reading the subway signs. The emergency brake sign is really unclear when to use it. It is called emergency brake, but the first rule is there is an emergency don't pull it.

Also I have been there, taking the train to get to an appointment, class, job, back home... and someone pulls the emergency brake of the train ahead or my train. There you are wasting your time, because someone fainted or got on the train sick or any other reason... (there are signs that advice you not to jump on the train when you feel sick).

I found this video that explains all in a funny way...
