I was the captain on the B-1900 in the east a few years back. During the 15 min downtime at the tiny, little, middle-of-nowhere airport, I decided to get an apple out of my bag, which was in the cargo compartment in the rear of the aircraft. When I came back inside the terminal, a 75 year old man asked me if I was checking my stash of pot. (Bizarre!) I calmly held up my apple, and told him we do not make jokes about drugs in the airline industry, and his comments were inappropriate. (There was all of five people in the place, including his daughter, the passenger.) Later, my f/o commented to me how polite and professional I was, and how well I handled the situation.
Well, imagine my surprise when the daughter deplaned at the hub and handed me a nasty note, saying I had embarassed an old man for no reason, and had acted wrong! I wonder what she would have said if the DEA had been called and swarmed the place. Funny thing, later that afternoon, she was again my passenger going back! I smiled and welcomed her aboard and forgot the whole thing. No note that leg!
However, this was all B.A., or "Before AmericaWest," the biggie incident that apparently replaced our security screening with sobriety checkpoints. Today, I, too, would submit to alcohol screening if someone "joked" about my sobriety, just as the FBI would show up if someone "joked" about a bomb.
