Phone calls especially. In theory you can make a phone call anywhere nowadays, but often you want privacy to discuss something sensitive or a quiet background for professionalism's sake. I'd love to see businesses have phone booths you could rent by the minute, although I don't know how viable that would be as a use of space in a major city.
