I'm checking out at PetCo. The card reader didn't make the GUNH GUNH noise. Lady behind me says "Oh I miss the days of only swiping." I scoff and say "Remember the old days when they brought out the Manager and the machine that went CHA-CHUNK and then gave you the messy carbon receipt?" She giggles, then startled says "You must be A LOT older than you look." I lean in and say "Oh, I am."
