Don't know whether you have heard this story, as I've said it before in this forum.
Once I was in the Beijing airport queueing to board the plane.About 20 people in the queue, I was about 10th in line.
3 people who seemed to be locals (2 guys and a lady) walked up and nonchalantly plonked themselves in front of the guy behind me. A little gap had opened up between him and me as he was looking at his hp.
I asked them to get in line, they ignored me.
I asked them again, the guy behind me also asked them, they ignored us.
I immediately went to the people behind the guy and told them that 3 people had cut the queue in front of them.
Immediately, they started shouting and scolding the threesome and there was back and forth bickering for some time.
Finally, the 3 lan lan go to the back of the queue, starring daggers at me.
If they were allowed to carry sharp objects up the plane, maybe I won't be typing this now..................
Sometimes, it's necessary to get others to help with the work.
