I wish this still existed in our world today. Unfortunately the world has "gotten bigger" and people are able to slip through the cracks and move all over and keep Sh^tting in a new place where no one knows you.
I am A "handshake man" myself, my word is my bond! It is awesome when you can make that happen these days!
Its rare but not gone. One of the guys that sales Indian parts still operates the old way. You call him if he has the part he sends it to you, if you like the part you mail him some money if not you send the part back. I tell my kids, no matter what you have in life you only own one thing, thats you word and you are only as good as your word.
I agree with the word is a bond, but keep this quiet or the government might make us register and tax each shake.
