ExXB Interesting point - you are predicting retaliation.
My travel is usually long haul. Most of my destinations offer premium passengers a "priority" service or, in the case of my most frequent destination, a frequent visitor card and finger print based clearance through electronic gates. Of course these are all destinations to the east of Europe...
My EU travel last year was Spain - PMI - where the non Shengan arrivals were dumped in a corridor and you couldn't work out which was "Others" until you got to the end of the (admittedly short) queue but it didn't matter as there were no jobsworths sending you back; and Finland where I had a pleasantly brief encounter with a facial recognition machine. Not enough experience, I'm afraid, to understand what it might be like to be an "Other".
