I learned about airlines pitching a fit about someone pouring thier own mini shot of vodka into a drink instead of buying from the stwaerdess over at: Joho
I think the mini bottle of vodka on the plane should be a non issue. The candy in the theater, I understand, the theater is a private place of entertainemnt that has a very limited business. The airlines however, although private companies, are acting as a form of public transportation, it is is lame to say you can drink on the plane, but not your own bottle.
I could see not allowing to people to set up a bar and start selling competing drinks (bar on a plane, nice thought), but really, when you could smoke on planes did the airlines say you couldn’t smoke your cigarettes?
