Tithing reimbursement —Wendy

A friend of mine told me she knows someone who's sole job is to write tithing reimbursement checks to those who "want their money back." Have any of you heard of this? I'm just wondering what I need to do to get my money back!

As I understand it, there's no way they could do that and maintain their tax-exempt status. I'd be very cynical of this friend's claim.
