I was on the north south line(red line) and at Yishun when a group of international student(secondary) board the train. And when the train door is about to close, one student(not sure what his intention was, probably to test the sensitivity of the train door) decided to pop his head out of the train.
Despite his friends tried to stop him, he insisted putting his head out till his friends forcefully pull him back. He is pictured carrying a grey bag.
An Uncle reprimanded him after that, and he wasn’t apologetic at all. Instead he argued rudely and sacarstically. This is such inconsiderate behaviour which might affect all the commuters. Due to his silly actions, it might lead to a train delay for all the commuters.
Not sure what school is this but hopefully the school is able to take disciplinary actions for this students.
