So, to wrap it up: Your local Post Office is probably closed. But that’s okay. Use the day for a walk to a postbox, or just enjoy the fact that you can’t send that package. It’s a tiny, bureaucratic holiday for your to-do list. And if you really, really need it open? You’ll find a survivor branch in a supermarket, like a little lighthouse in a sea of shutters.
Next Bank Holiday Monday, when the question pops into your head, just smile. Remember the postboxes. Remember the supermarket stamps. And remember that sometimes, the best answer to “Is it open?” is “Does it matter?” The mail will wait. The world won’t end. And you’ve got a whole day to chill. How cool is that?
