Whenever I’m at a hotel or other large buildings I can’t help but notice all the inconveniently located light bulbs. I wonder what kind of equipment must be necessary to change them. I wonder how large a building has to be before they need to hire someone full time just to deal with ordering and changing all the different bulbs. I imagine the storage room of shelving filled with all the different bulbs necessary to keep on hand. Then the elevator door opens and I go back to my life.
