Frustrated Pilot?
No. But I deal with (what sounds to be) many of them every day. And that is before they suffer my vectors and speed control! Many they must be really pissed off when they spend their 25 minutes on the tarmac and then launch back the way they came only to hear my voice again!
Do I miss flying in crap weather with crappier passengers for crappy money? Sometimes. Thats why I have my own aircraft that I fly in great weather, with a great passenger, when and where I want to.
Frustrated pilot? No sir.
But I sure know a few.
