The following story appeared in my Google Alerts update this week, and – after careful consideration – I decided I just had to throw in my two-penn’orth.
Basically, a columnist wants the company to remove the apostrophe from their sign. On the face of it, I agreed at first, but then realised it wasn’t quite as clear-cut as it seems.
How many boys are there? That must be the nub of the question. If there are more than one, then – yes – the apostrophe needs some amendment. But…should it be removed altogether or simply placed after the word boys?
This establishment could be one, singular, boy’s shop. It could be several, plural, boys’ shop. Or, Pretzel Boys could simply be the title of the business.
Think of The Fabulous Bakin’ Boys. 
This is the company’s name – ok, they have an apostrophe elsewhere – we’ll not go there in this post!
But, maybe we’ll leave the last word to Sainsbury’s, and their response to Mr M. He asked them why their name has an apostrophe – read their reply here:
