I work part time for the USDA getting Agricultural Statistical Data from farmers.
I call a LOT of farmers ussually at night, often late as thats when they are home.
I always identify myself & who I'm calling for first. I always indentify him by both first & last name.
Anyone who does NOT do the same for me gets hung up on.
Most of em are easy to spot, they have a 3 second pause while it switch's over from the computer dialer to the phone.
If your on the ball you can hang up before they are every on the line.
Do not call list WILL be a reality before the years out. The public will demand it.
But I agree that it needs to be done right the first time.
