I was traveling through Pennsylvania a few years ago and stopped by an ACME market for snacks. The store lost power and their electronic card processing was knocked out. They suggested I pay by check. I didn’t have a checkbook (hell, mine is growing roots in my desk drawer), so they broke out the old manual credit card gadget? Remember those? They place your credit card just so, put a slip of paper on top, manually set the amount and then swipe it for an impression of your card! It was a treat - I hadnt seen one of those in 20 years!!!
