I'm not substituting anymore, but cell phones are still a pain in the #@*. When you're driving behind someone and they're going slow as molasses, and weaving all over the road.....chances are they're talking on a cell phone. Go ahead. Check it out next time you finally pass someone you've been following for the past 700 miles. They'll be chatting on their cell phone totally oblivious to the road or the person behind them going into a rage because they need to GET somewhere (dammit).
Today at work, I had a woman who was trying to do some fairly complicated business with me, yet kept answering her cell phone and chatting while I was trying to do her transaction. We are supposed to be extremely friendly and polite to all clients so I didn't go with my first inclination, which was to say, "you go ahead and finish your conversation and I'll just wait on the person waiting behind you. You can go to the END of the line when you're done." (Although I thought that was fairly polite!!) Instead I just asked her for info (address, phone number) while she was talking and she finally said to the person on the phone that she'd have to call them back. Thank you!!
I'm not totally anti-cell phone. I own one myself. But I would never talk on it at the counter of a store, in a restaurant, or while I'm driving. I have a little common sense. Apparently most people don't.
