I was chased out into the snow in January by a fire alarm in a hotel in Cambridge, Mass., at about midnight. I threw my coat over my nightgown, grabbed purse and shoes, and shivered outside with the other guests for a good half-hour before the all-clear.
Another time, I was in a hotel in, I think, Arizona when an alarm went off mid-evening. The group I was with was having a costume event. We filed out into the parking lot and stood there for what seemed like a long time, but maybe my perceptions were somewhat distorted.
Neither of the incidents came to anything. If there even was a fire, it was put out fast. Still, it was a bit of unexpected excitement.
