And usually someone else has to approve the change.
Many years ago my cell phone company changed insurance carriers and I guess they had to inform their customers of what the new coverages would be, because I received a 30-40 page booklet in the mail. I dutifully tossed it onto my desk and forgot about it. Fast forward a few months and I'm sitting at my desk bored out of my mind, not feeling like playing any of my computer games and having nothing else to do. It's a testament to the state of my boredom that I looked at that booklet and thought, "I'm really bored, let me read about my phone insurance coverage."
The coverages started out pretty normal. I was covered for
fire, theft, breakage, loss, etc. Then it went on to tell me that I wasn't covered if I gave it away, or if the FBI confiscated it. A few pages later, though, it got really strange. I was reading down the page and it said, "Your phone is not covered if it is destroyed in a nuclear explosion..." I paused to take that statement in, then kept reading and it continued, "...unless the nuclear explosion starts a fire and the fire destroys the phone." Because of course then I would be covered as it was lost in a fire.
All I could do was stare at that sentence and think two things. First, given the proximity of my phone to my person at all times, it wouldn't matter if it were destroyed directly or indirectly by that nuclear blast. They wouldn't need to worry about me filing a claim. Second, not only did someone have to think that up and think it was a good idea to put into the book, but at least one other person had to read and approve it.
I really can't think that there would be very many situations where a nuclear explosion happened and the phone was far enough away from the owner for that person to be in any condition to file a claim that phone was lost in a fire instead of directly.
