I was just reading this to Mr K (not the one who’s a member of this forum!) and he said Austria has started doing random checks of people on the street.
This should end well!
I remember talking to a coworker from the Netherlands when they were here in the US on business. One of the first things they thought to mention as “weird” was that Americans carry around ID (i.e. driver license) with them everywhere they go. How’s that working out for them?
