Today in the elevator in my building, I was backing up against the back wall of the elevator as it went up, but I backed up too far, all the way into the wall, and there was this "clunk" sound when my G30 hit the wood rail on the wall through my jacket. It was very quiet in there without any elevator music, and I'm sure the others in there wondered what was hard enough on my person to make that sound. It was a little awkward...
