Cell phones are annoying and it's rude to be on them- I knew it wasn't just me!

I know I just recently posted about this, (click here), but obviously many agree it's an issue because there is yet another article on it!

On a personal level, I find cell phone users to be among the most rude.
Working part-time as a cashier, it has become a pet-peeve of mine. You greet people, ask them how they are and if they needed anything else, and all they can is roll their eyes at you for disrupting their conversation, throw their money on the counter, and not even responsd to you?!
Well, hey, thanks a lot!
I'm here working and being polite, and you left your manners in a little wedged place in a hole.
You can't even say hi or thank-you!

From the article,

"This world without wires allows technology to ride shotgun throughout daily life, which, for the most part, is a convenient and useful tool. But it's the lack of a politeness protocol that has some up in arms."

I am one of those up in arms!
