I don’t know if you pump your own gas these days or not. I suspect you do, like most of us these days, unless we visit to New Jersey where it’s against the law to do so. This fact of modern life was satirized in a scene from one of my favorite movies, Back to the Future, where Marty McFly is astonished to see four attendants at a filling station launch themselves at a car to check the air in the tires, clean the windshield, pop the hood to look at the oil and coolant levels, and take the driver’s order for gas. Now, those were the days!
Of course, if we’re paying cash, we have trudge over to the attendant—the horror of it all!—and schelp back to the car where we can then fill the tank ourselves. If we’re using a credit or debit card, our lives are somewhat easier. Indeed, if we used plastic to pay for gas, we rolled up to the pumps, got out, swiped our card through the reader, waited for the screen to respond, chose a grade of gas to our liking, and started pumping. Those days are gone, apparently, because the little magic screen now asks us to enter our zip code, a security measure in case we have stolen our own credit card and are trying to use it a half mile from where we live. I understand the need for this little addition, since having a credit number used and abused by someone else does not make for a good day in the life of the card holder, but I also have to confess it took me back a bit when I first had to enter the number with my little index finger. The screen also told me that if my postal code included letters, I had to see the attendant. Huh? I thought. There ain’t no letters in a zip code. What’s with that?
As it turns out, there are letters in postal codes of many countries around the world. Say you want to send a nice letter to Oxford Press in Oxford, England. You write your nice letter, put it in an envelope, and after putting on proper postage, address it to:
Oxford University Press
Great Clarendon Street
My little experience pumping gas showed me, once again, there is always more to learn. And I’m glad. Think how insufferably dull life would be if we knew all there was to know by the ago of, say, 30. As it is, the older I get, the less I think I know. And that’s not a bad way to be.Please note that the “postal code” includes letters and numbers, so they got it about 1/3 right. Not bad for a former mother country. They’re not alone, however, in using letters: about 250 other countries do as well, including, in some cases, the U.S. So, we’re in a minority by using only numbers. Who knew this? Not me!
