I had a deal with one engineer on my team, when I used to do that boss crap.

Their body had to be present in the meeting, but they could keep working on their laptop.

This was because WAAAY too much of the silent information about the company products was on their mind and it was by far the fastest way to get it out.

I could just quickly refer to them for 15 seconds to clarify how something actually worked and keep on with the meeting.

...also they once got bored during a sales meeting and coded a full-ass PoC about what the customer was asking during the meeting. That kind of person.
