I don't think anyone speaks perfect English (apart from The Queen of course *doffs cap*). I like the way people corrupt it sometimes, whether on purpose or not. It can be a part of their personality. If you get too anal about it and correct people all the time that can become tedious. I suppose some are more tolerant than others on this matter. It can also be down to how educated you are as to how much you know about the language. If you skipped a lot of school you're probably not going to know much about split infinitives.
