Technology doesn't always change our lives for the better. Sometimes it can bring out some bad behavior.
We've seen it at the park. We've seen it at the store, even at work -- people being rude while using their cell phones.
Jim Boulden takes a closer look at the issue.
Texting, talking, surfing, all on the go. We all do it.
Here at Malletti's, Italian takeout, they do good pizza and they don't tolerate bad manners.
Owner Antonio Verruto decided to put his foot down and put these signs up three years ago.
So, if I come in like this and I order a pizza, what are you gonna say to me?
I'm not gonna serve you. And if you insist, I'm gonna chuck you out.
You're gonna chuck me out?
Of course.
But you know, this is today's life. I mean, I want... I need to be on my phone.
This is your life; it is not mine.
It's rude if people walk in a shop and they don't look at you, they just keep pointing at the product.
People they were concentrated on the phone, on the people who were on the phone, and they completely forgot what they ordered.
It's one thing to be using your device on your own time. It's altogether different when you're in the office.
So, as an experiment, we set up a camera inside CNN to see how some of my colleagues react during a meeting.
No surprise, perhaps. In a room full of journalists, a half dozen of them checked e-mails or surfed on the iPad.
So, is that behavior always appropriate in meetings?
If it is related to the output and improving the output of having the meeting in the first place,
then that's exactly the kind of collaborative use of technology that makes it so powerful.
Etiquette expert Liz Brewer hates mobiles in meetings,
but recently had an even more dramatic encounter with a ringing phone.
I was at a funeral and... the other day, and it was the wife's phone.
Wow.
I was doing the eulogy. I said, "He's obviously... Sam's obviously ringing you from the dead."
Says Liz Brewer, when meeting, people should look at one another in the eye and not focus on a screen.
