Having experienced it myself, we did have a passenger strip down, and became so uncomfortable he lay on the floor. He had a load of chocolate goods that were packaged and on a seat, that he was taking to the destination for Christmas presents. They were all melted.
On another occasion, we didn't go to emergency pressurization, but we did have a duct separation at the back of the cabin. It resulted in bubbled and burned cabin trim and parts of the interior that were hot enough I burned my hand when feeling for the heat. I had been summoned by a passenger who felt it was too hot; the passenger was right.
When I experienced a depressurization due to a door seal failure, the resulting noise was loud enough that neither I, nor my F/O, were able to hear ATC.
I experienced emergency pressurization one night during a cargo run, shortly after takeoff from a mountain airport. It was loud, and hot.
Each of those events occurred in different types of aircraft.
