I expect he knew that but didn't expect to have to call 911, so didn't have the phone with him.

It may not have mattered. Most elevators I've been in are, essentially, big metal boxes. These
boxes tend to block most radio fairly effectively. In my building, I get "4 bars" until I step into
the elevator. Doors close, signal strength drops to zero.

man ive missed being away from this board for so long.
so much to catch up on now better get another cushion for my seat.

id definitely say carry a bottle of water on you at all times, small flashlgiht like the photon etc.
i always carry stuff in my pockets like mints, not really food but can help you feel a little less miserable with something to snack on.

personally id either use the large metal clip holding my keys or my boot to keep slamming on the walls/door so i attract some attention..
