They were queuing at two different lines and were talking across to each other.
The queue at one of the line was moving faster than the other.
The lady at the line which is moving slower decided to cut queue by crossing over to join her friend at the faster line.
The custom officer at the faster line saw her and signaled to her to go back to her original line.
Instead of abiding his order, she tried to hide herself behind her friend.
When she approaches the counter, the custom officer signaled to her to go back to her original line again.
She obediently went back to her original line but her face was as black as charcoal.
The irony is that she is just two persons behind the faster queue and four persons behind the slower queue. And she was not late for her flight. Why cut queue when there's not much difference in clearance speed between the two lines? Does it make her happier to clear the custom faster? Does it make her feel like a winner? Or feeling of winning by being able to cheat?
And have it ever happened to you that the queue you thought was faster ended up being slower?
She should be glad that the custom officer did not ask her to re-queue.
