I am surprised too. Self checkout only intensified recently in my country. What is surprising is that the dislike seems to come from the corporate side. So it exist since 1990, and just now they realised they are loosing money on it. Pretty weird.. But I'm all in on big corpo losing money because they didnt want to pay wages.
Mark my word: they installed self-Passport machine in Paris airport in planning for the Olympic tourists grand arrivals. It will be a disaster!!
It doesnt work, it is slower than having an human check your pass, and a lot of travelers will be very angry at thoses machines. Plus I suspected you can trick them easily if you're a criminal
