I suppose some degree of commerce would grind to a halt if telephone 
solicitors weren't able to call people at home during dinner hour.
But that doesn't make it any more pleasant.

Now Steve Rubenstein, a writer for the San Francisco Chronicle, has 
proposed  "Three Little Words" based on his brief experience in a 
telemarketing operation that would stop the nuisance for all time.  The 
three little words are "Hold On, Please."
Saying this while putting down your phone and walking off instead of 
hanging up immediately would make each telemarketing call so time-
consuming that boiler rooms would grind to a halt.  When you eventually 
hear the phone company's beep-beep-beep tone, you know it's time to go 
back and hang up your handset, which has efficiently completed its task.  
This might be one of those articles you'll want to e-mail to your 
friends.  Three little words that eliminate telephone soliciting.
