The one problem as I see it with D2D fundraising / religion is , your always caught off guard .They always seem to catch you at an in-opportune moment , one that your not prepared for .
While that might be advantageous to the caller in some cases overall I think it is detrimental to the organization doing it. ..Its off-putting
And now with the tele-marketers ringing you up over and over again with the same message you have rejected a thousand times before ,a sane persons patience runs thin .
And that is definetely not good for the product that is being sponsored .
Getting back to the JW religion ,I would love to know , how many converts are really made through D2D witnessing in a year in first world countries.
And the same can also be asked of the Mormons ,and the Seventh day Adventists,if we could get true reliable statistics about this , it could be revealing.
Those three religions are the ones more likely to knock on your door.
