Worked a few years in my early 20s at a C-store with gas pumps back when using a gas-brand credit card meant you had to give your car license number in order to process the charge. With a lot of repeat customers, I had 400+ plate numbers in my head. Remembered the cigarettes they smoked, the kind of milk they bought, and the kind of candy their kids preferred. Now? I almost can't even keep my own zip code in my head! Maps, markers, and lists are the rules of the day.
