I think you'd want the other person to leave. That would probably get you
booted from the plane/bus/train.
Getting booted from a plane or train would suck especially a plane... I guess it just depends on how annoying the person was. Still though, after the timer hit's 0 i think something drastic should be done to get your point across to the person.
Then again if they gave me a parachute, that would be awesome.
"The people cannot be [...] always, well informed. The part which is wrong will be discontented, in proportion to [...] the facts they misconceive. If they remain quiet under such misconceptions, it is lethargy, the forerunner of death to public liberty. What country can preserve its liberties, if it's rulers are not warned [...] that this people preserve the spirit of resistance? The tree of liberty must be refreshed from time to time, with the blood of patriots and tyrants."-Thomas Jefferson
