Ok. I have a new pet peeve. When people call and hang up. It's sounds trivial, but when it happens 50 times a day or more, it gets old. Does it really require that much effort to say, "sorry, wrong number" or "I'll call back later"???
Did no one teach their kids phone etiquette?!?!?!
I'm so tempted to start writing down the numbers of those who call and hang up (before the number disappears of the switchboard...) and calling them back.
If I really wanted to be mean I could go to the fax machine on my break, and send faxes to their cell phone or home phone or whatever number they were calling from. I bet they'd love that.
