When I was a child growing up in a small town in Wyoming, the local bank used to leave blank checkbooks in the checkout lanes at the grocery store. I was always fascinated at how my parents would walk up, sign a little piece of paper, and leave with all these groceries.
I asked Mom and Dad for one of those checkbooks, and they wound up bringing one home one day. I was ecstatic! I immediately wanted to know what I I needed to do to start getting all the "free" stuff I wanted!
