Polling and anonymity

Surely I'm the most polled person in Bermuda, and that tap tapping in the background is me logging the questions.

But I have a complaint for the pollsters: ending your calls with this series of questions obliterates any pretense of anonymity and always leaves me amazed:

What is your age?
What is your gender?
What is your race?
What is your income bracket?
What Parish do you live in?
What is your Postal Code?
So that I can confirm for my supervisor that I conducted this interview what is your first name?
And I reached you at the following number: 441-23X-XXXX.

Yes Total Marketing Group. That would be you.
