A few days ago, Mr. Improbable posted the following dialogue to his Facebook page (I’m reformatting it for easier reading):

Phone call received here 1 minutes ago:
Me: Hello, Improbable Research.
Caller: Hi Marc, this is ___ from ___. How ya doing today?
Me: Fine
Caller: Blah blah blah
Me: Do you have any idea who we are or what we do?
Caller: No.
Me: Well, it’s been… nice talking with you. Please put us on your “Don’t Call” list, if you have enough information to do even that.
Me: [hangs up the phone]

A few minutes later, he added this comment:

And now I’ve gotten an email from the man who telephoned. The email says:

Hello Marc,

Thank you so much for time on the phone! I found it very useful to know more about your company, and in the future will do research on the people and companies that I call so I don’t have to get responses like yours.

Rest assured you will not receive another email or phone call from us.

Warm regards,
_____________

I have to say, I think that was rather well-handled all around.
