Turn of phrase here, fair point. I meant "if you want to review, then it will be additional time outside of doing your paid work." Second question is an interesting point: what happens if you don't review? I can tell you that it is certainly the case that a lot of academics don't do reviewing. Given the amount of reviewing I and my colleagues do, there must be others who are not doing their fair share (say 3 x your submission rate) of reviews. What are the consequences of not reviewing? Perhaps you can be seen as a freeloader, some social cost, but mostly people just won't know unless you're replying to them directly.
