Every phone survey I've gotten goes like this, more or less:
"Hello, Mr. Leekus?"
"Lileks. It was Leekus but I had an operation."
"Thank you! I'm from Meaningless Generic Company Name, and as you can tell from the background noise, this is a hellhole boiler-room whose ceaseless din reminds one of a chicken coop. I numb my pain with alcohol when I get home, but for now, I'd like to ask you some questions. Do you have the time?"
Finally! I'm being polled!
"Sure," you say, but not too eager — you don't want to sound as if the last conversation you had took place three weeks ago, and consisted of pushing the YES and NO buttons on the ATM.
"Thank you! These are questions about something that concerns you deeply, and about which you have detailed, personal knowledge. Before we continue, do you or anyone in your household work for a company that is connected in any way to the subject we're discussing?"
"Uh, yes. That's how you can be sure my responses will be useful."
