What does this short conversation mean? Waiting for help A and B were having dinner with B's boss. And after that A said the following things. A: I do not like your boss. So if you don't mind, this will be it for me on your working things. So what does it mean by saying "this will be it for me"? Is it to say this would be the last time for A to attend B's work things of this kind? And more generally, I can use it when saying that I've had enough of something, right?
