People in other countries are generally more reserved when having conversations in public. Most people keep it short and hang up.
However, American teens and people who thing they're important will talk so damn loud over the plane that someone's gonna get their butt kicked. I've had to deal with listening to people using the Airphone and that sucks. And at least it's mostly gone now.
At least in Vancouver we have many different ethnicities talking at the top of their lungs and having very long conversations on public transit all the time.
Mostly these people aren't even from North America to begin with. -- Xenophase - British Columbia's premier online gaming community.
