Whoever you are, if you’re in print you have to get rid of these. I can help, whether it’s a book or a website. I’ve lost count of the number of high end websites with an apostrophe in the wrong place, or a restaurant awning with a double S in Prosecco…. It’s a terrible look, undermines whatever you are trying to say, and is so easy to correct (except possibly for that restaurant). Rogue commas and bad spelling have no place in print.
