You never forget your first time. Last night, I was asked to present my completed Covid-19 vaccine card in order to enter a restaurant sans mask. I had the card on me (plus a digital version), and once it was checked against my driver's license, I was able to walk to our table like in the Before Times. The whole process took less than a minute. Honestly, the hostess could have saved a bit of time by scanning the nanochips the government injected into my bloodstream when I got my second vaccine shot, but whatever.
