Had the same experience flying SFO to Santa Rosa and again Philadelphia to Atlantic City. Both of those were twin Otters. On one of those the co-pilot turned and looked out from the cockpit (no door, just a curtain) and asked: "How's everybody doing back there"!
I can't remember which puddle-jumper itinerary it was, but I vividly remember once a pilot emerging from behind that curtain, visually guessing everybody's Body Mass Index (BMI), and reassigning folks to other seats so as to "balance the load." It, um, really boosted confidence. Not. I'm a smallish woman so I got to keep my seat.
