additional info for thought:
If you miss boarding the train, there’s always a next one. But if they miss their stop, it’s a hassle to make a U-turn.
Don’t be selfish and also, don’t cut the queue.
In case no one taught you ; don’t stand right in front of the train door or block the middle of the platform box. Let people get off first before you enter.
If the waiting area is too narrow to queue behind, queue to the side
