I've read on here many times about immigration workers not taking the migration card so I've tried many times to leave without surrendering it. Every time and I mean every single time over the last 5+ years I've done this they just look at me with that "well...where's your card" look which I then produce and apologize. Maybe it's because I'm only at SVO or maybe I just have that look about me but I always seem to invite the "what kinda smart guy are you" look from them.
