I've fought this battle so many times.

My most recent battle was being told to implement Scrum and agile practices. When the subject of standup NOT being a status update came up, and I forcibly told people to keep their updates brief, it was changed to a "Sync Meeting" that lasted over an hour. Apparently, despite delivering stuff faster, being able to track velocity and ensure we're not overextending ourselves each "sprint", and actually knowing what we're delivering through actionable tasks - we're not doing agile any more...

It took me a year but I broke my team of this habit. The trick was to remind them that the parking lot shouldn't be scheduled. The whole point is that you continue conversations organically so that it's more like the beginning of a working session instead of the end of a meeting.
