I'm not sure why you attribute this to self-importance. It's a real risk and a fair concern. USA border and immigration officers sounds hostile and antagonising from the stories I heard on Twitter (over the course of the past week). It will take me close to 24 hours to reach American soil. Depending on my luck, I might either: a) pass without issue, or b) hand over my phone and passwords and/or complete CS puzzles (which may also include period of detainment) They can turn me back for any reasons and I would have lost thousands of dollars: if my answers were unsatisfactory, if there were some prejudice against my look, or even if the officer(s) were having a bad day.
