We live in an Age of Disgruntlement and when I dine with grumpy people, I listen to their gripes and when they stop to take a breath I talk about the great progress made in my lifetime, which of course irks them no end. For one thing, the cash card. We used to go into the bank and hand a check for cash to Mildred the teller with her pert hairstyle and starched blouse, her specs hanging on a chain around her neck, and she’d wrinkle her mouth and peruse the check, questioning the wisdom of handing you money, and eventually she’d count out your thirty dollars and say, “Now don’t go spending it all in one place.” And now there are ATMs everywhere you look and you slide in the card and get $300, no look of disapproval.
