I also experience this, and the scrum master gets frustrated also. But the ways I see it, a lot of the teams chills together for smoke breaks, and those basically serve as a bunch of small informal retrospectives on a daily level. Unless a sprint went really badly and there needs to be a real discussion about it and if its a structurable problem, most retrospectives are not so useful if the team has a natural communication structure.
