Once it happened the same situation with a family father mother and 2 children, one is around 10 or 11 and the other around 5 or 6. They have not purchased ticket for the second one. when TT asked for ticket parents told he is below 5. TT nodded his head and continued checking other passengers ticket. after finishing the checking he was about to leave the bay he casually and in a friendly manner called the child and asked his name, for which the child replied then his second question was in which class you are studying the boy replied FIRST standard. Immediately he took the receipt book from his pocket changed ticket+fine etc.....and he told to the parents if you have straight away told the truth i would have neglected it.
