Has it occurred to you that merely "Getting Stuff Done" isn't a groups primary motivation? Or that they are getting something done but it's not what you'd deem important, or being done at the pace you'd prefer?
Believe me, if you sat in on one of our games? Most sessions you'd likely say* that we'd wasted 2hrs out of our precious 4.
But here's the thing - even at our most unproductive, those weren't wasted hours to us. We've got our own pace & style we're happy with and there's always next week.
Maybe this group, who's allowing you to listen in, is like this.
*That's assuming you survived the aneurysm you'd surely suffer as we don't phrase things as I know you prefer, players ask to make skill checks, players simply declare their making skill checks, players ask questions, players have characters with backstories, etc etc etc
