My pdoc schedules for 30 minutes and keeps you till he's satisfied that you're OK. The second time I saw him, I was in his office for 90 minutes. People were stacking up outside his office, and when I commented on feeling bad about that, he said, "They'll wait. We're not done yet." Often I was there for 45 minutes or an hour, not just the 30 that had been scheduled. To me, that is the humane way to deal with psychiatric patients in crisis!
