Yes, only 4 weeks ago when checking in at IAD for CW back to LHR with my teenage daughter. There was a long, long Y queue and only 1 pax at the CW one when we turned up. So still dressed in our holiday clothes (t-shirts, shorts etc) we walked past the Y queue and went and stood behind a smartly dressed businessman at the CW desk.

My daughter turned to her right after about half a minute and quickly turned back and whispered "Dad, they are all staring at us". So I turned round to see what seemed about half of the Y line icily staring at us. However, to be fair, no one actually said anything....but they didn't need to - their feelings were obvious
