Waterstone's, the largest British book chain that was founded by Tim Waterstone is now changing it's name to drop the apostrophe. It will now be known as Waterstones, which is probably how most people would remember it anyway. It will also make it easier in the digital age where it has already dropped the apostrophe online.
However, the Apostrophe Protection Society has said that it is grammatically incorrect and they should have left it in.
So, should Waterstone's leave the apostrophe in, does it matter and are some people just a little too hung up on English grammer?
