HAHA this thread is awesome.

Doc Savage your comment is the greatest by far, "remove all violators immediately..."

Surprised how many people are ok with the concept, perhaps more time on a train will change peoples' opinions. I've never felt more likely to enter a homicidal rage (figuratively, of course) than on a nearly full train in Italy. EVERYONE was talking and no one at a reasonable volume.

That said, I've had seatmates on business calls who I barely noticed and may be guilty of doing the same once or twice when it absolutely couldn't be avoided.
