Went through FRA a few weeks ago on a Schengen transfer. Security was friendly and professional. My laptop had to come out of my EZ-Scan briefcase as they are not recognized in Germany (said the female security officer apologetically), but we had a nice exchange about it and she ended up asking if she could show my bag to a colleague of hers who had not seen one before. Meanwhile something in me buzzed the WTMD but I had a brief, civil secondary and was on my way in two minutes. No shoes off, no belt off, nobody touched me inappropriately, nobody looked like they were poised to steal my stuff. It was like we were... all adults. Very strange and different experience from someone used to TSA.
