The Beijing Airport is trying to get feedback from the passengers. But this very commendable initiative is just slightly biased…. since you can vote before being granted entry and receiving your passport back from the Customs’ officer.
As you can see, in addition to voting you can even leave a “voice” comment. Can you imagine complaining to the machine right in front of the officer?
That’s going to create loads of funny situations, but totally biaised for sure!
