Long ago I must have received the hint that it's not a good idea to go commando when sleeping -- not that I ever needed such a hint.

Last year I had a hotel evacuation in the dark hours of the morning. I was literally among the last ten percent of the guests to get out of the hotel because of a few factors. What didn't delay me was my grabbing of my coat, which is where I had -- as per my routine -- kept my primary passport+secondary phone+bank cards in a pocket along with a room key (since I actually always insist on two room keys out of habit ever since dealing with hotels that require the key to be left in a slot to activate the room lights). It was a cold winter morning (for others) for the 30-40 minutes it took for the firefighters to give us the all clear to re-enter. I guess one upside of preferring to be where the weather has most people wearing a jacket/coat is that I'm better prepared to evacuate in the middle of the night.
