I have relatives near the Missouri Valley area that had a story about Warren. He was riding in his Porsche behind his convoy of RVs headed up to Okoboji when one of his tires started to leak. He stopped into this ma and pa repair shop and had it patched up and when he went to pay he wanted to use his credit card for the $20 charge. Well of course they didn’t have one and they suggested he might use the ATM up town to get cash out. He refused and said he only pays credit but he’ll get them the cash as soon as possible. So a couple weeks later he has a gopher of his drive all they way there to personally deliver a crisp $20 dollar bill, not a cent more.
