Nope, some guys (and women) who use computers for work and who have tech hobbies also have physical hobbies and can work labor.

Though, this is a great application of smarts as a lever. Even the most hardened labourer wants their job to be easier. This one just happened to be developed by women. They'll realize they're cutting at least 50% of their potential market out, and will want the profit, and will change their stance. Hopefully.

I've been in secondary a number of times (business related, frequent border crossings).

They're not interested in you as a person, nor are they interested in holding anyone. They're entirely interested in detecting fraud and crime, and the people are secondary to that.

When you're in there, keep that in mind. They don't care about you as an individual, in a completely neutral sense. Just take in the surroundings (ever notice that it's just a normal workplace to them? Seems weird, but they're mostly relaxed at the office), and answer questions comfortably and respectfully. You'll be out in good time, depending on the lineup.
