When I cross borders I'm almost always very tired, very stressed, I feel dirty and nauseous. These are things that make handling other people difficult for me. Of course there is going to be someone who reacts badly, but you would think that they have professionals at the border that know this, from what I've seen when disembarking in London there are people who know how to handle these things. I've seen the same situation being descalated in 10 seconds. I'm guessing there is little pay and pride to be had for a border guard in the US, so little incentive for being anything else than a git.
