Though I've never worked in the commercial air industry, I have briefed, boarded and flown with thousands of people in my fire career (that'd be forest fires) Most all of it is with helicopters, but some with fixed wing also.
We are given exemptons (by the FAA) for hazardous materials, such as chain saws, fuels, fusees (aka road flares) batteries, etc in order to do our job. We (especially myself as a helicopter manager or helibase mgr) have to adhere to some pretty strict rules. And we gladly do so. Not because the FAA tells us to, but because the environment in flight is a precarious one. Should something go wrong, you can't just stop the show and deal with it. If you want to get a helicopter pilot beyond nervous, have him start smelling 50:1 chain saw mix or smoke from a jammed PSD machine (used for prescribed fire) over crappy ground or continuous forest where there is nowhere to land for miles. Or tell him an article just flew out a window (and by definition towards the tail rotor).
Now, put yourself at 30,000 feet doing 500mph in a jetliner with 200+ people in it who speak 30 different languages, who you have never met before, who you know nothing about and who tend to see an airplane as little more than a bus to get across town. My firefighting situation is benign by comparison. I generally only fly people who know why they are there and they are getting paid to behave and go by the rules (even so, they make plenty of life-threatening mistakes around helicopters, in spite of the rather severe safety briefings we give). Yes, I can see where you certainly know yourself well enough to know you are not a threat. But the airline personnel don't know that.
Aviation has to have its rules. Pilots are some of the most anal people you'll meet- in a good way. I won't fly with sloppy pilots and in my career I have had one or two sent home (same with timber fallers). But pilots are also very confident and intelligent. Just the kind of person you want at 30,000 feet- or at 300 feet.
In the future you might want to medicate while in flight and not in the terminal lounge. Or practice meditation.
