Earlier quoted context omitted.
I agree with the general spirit of your post, however: Amsterdam Schipol has (a lot of) scanning machines as well. Germany has more freedom in certain areas and less freedom in others. (you can't take your empty bottles to the recycling bins on Sunday for example)
of all the things bothering me about Germany, this is not one of them. More the fact that nearly all shops close at 8pm and everything is closed on sunday.
Stores were closed on Sundays, things closed earlier in the evenings.. We survived, we planned ahead..
Now everything is open all the time. Malls are open on Christmas day, even on New Year's Day!
When do people have time to spend time together, to relax, to not be consumers but be people?
I kind of wish stores were still closed on Sundays..
