Here's a hot tip for marketers who use phone surveys - my time is valuable, so if you want me to answer, you'll have to:

• Use people who speak English well. If I can't understand them, and they can't understand me - then I don't have the time to be bothered
• If your people ask a question, and I answer categorically (i.e., I say "I have one child"), then the survey shouldn't proceed with questions that ask about other children. In other words, pay attention.

If you can't be bothered with those two things, I can't be bothered with your survey.
