I got an email that had a line at the end of it that said "Think twice before printing this email to save paper" (something like that). I didn't notice it at first, but when I printed the email the only thing that was on the second sheet of paper was the line about saving paper. The line about saving paper literally wasted a piece of paper.
That's why I pick and choose what I want to print from an e-mail. Most times I only need one page out of three or four. I hate ending up with a sheet with only a line or two of useless info like that. Your example is a classic.
