The next time you look at the calendar and see a bank holiday looming, don’t fight it. Don’t Google “does the sorting office open?” eight times. Just nod wisely. Prepare on Saturday. Or, better yet, enjoy the break. The post office is closed. The world will not end. But if you really need a stamp, ask your neighbor. You’d be surprised how many people hoard first-class stamps like they’re treasure. And on a bank holiday, they basically are.
So, to answer the question one last time: No. The post office does not open. Go home. Make a cup of tea. Your mail can wait. It’s not going anywhere. Except, you know, stuck behind a locked door until Tuesday morning. Good luck.
