No, I still have both of mine. 

Yesterday I stopped at lunch for Wendy’s. One person in line in front of us. Guy places his order, hands over the credit card, and the cashier is just about to hand the card back when he decides he wants two more of something. Rather than just doing a new order (which seems ok in this case), she apparently needed a manager override to edit the order. She did this by calling to the back “I need a thumb”. It looks like they require a thumbprint for the override, seems smarter than key or a pin number. I’m now amused thinking about how things take on a life of their own sometimes. Did they pick the thumb as least likely to be mangled? Or so that the cashier wouldn’t be yelling “give me the finger”?
