That's a bit of a snotty review there from The Guardian.

I just can't believe this. I got home tonight and found a note behind the door from the Killearn Co-op. They are opening at midnight on Friday for the launch of the new and final Harry Potter novel. Staff will be wearing costumes, customers can join in the fun. There will be a Harry Potter tunnel which kids can enter (at midnight??), with great effects inside. After exiting the tunnel, there will be samples of witches brew and wizards treats!

Bear in mind that Killearn is a teeny place, and I can't help but feel that the staff will outnumber the customers!
