You are in a big line to get a railway ticket. If you estimate with the speed its going on it will take about 30-40 mins for you to reach the ticket window and then get the tickets.
There is nothing much around to pass time and also standing alone is a boring job. Suddenly to your surprise you see a new ticket window opening. It takes few seconds to figure out what actually happened and the moment you realize the opening of new window you sprint to that new window and be the first one in the new line. Your boring waiting time is saved and you get the ticket in mins.
Chhoti Si Baat!!!
