I do, it saves time.
Plus, it demonstrates leadership in these days when everyone is equal. If the Captain is prepared to knuckle down and help the crew on a turnround to save time and expedite the day's duty, the crew will (hopefully!) be equally motivated.
But more to the point and probably my biggest motivation for it; it's the only time you get to figure out what's been going on in the cabin. To hear the CC talk amongst themselves about the problems they encountered during the flight; the odd noises they heard, the difficult passenger they had, they smelly oven they noticed....
It doesn't match an open flight deck door policy for exchange of information, but since that's gone it's the next best thing.
Different on a big aircraft with very experienced crew, you need the purser/no 1/crew chief to filter all that out for you, decide what's relevant, deal with the problem and inform you as it all happens. But when the no 1 has been flying for 18 months and the rest of the CC for 6 months, you have to keep more of a handle on the cabin.
