Except for an occasional cigar I am not a smoker. But I can imagine that it’s frustrating that you have to hand in your lighter each time you board a plane. If you’re a smoker and land at Shanghai Honqiao Airport you are lucky: At the exit of the terminal you can choose another one from the lighters they confiscated there from departing passengers.
I noticed that many people took a lighter from the pile, I had to wait about a minute in order to take a picture without any passengers in it. I think this is a great idea, otherwise the airport would probably throw the lighters away or auction them off.
