Think about your phone. Do you plan how you'll charge that quickly? Do you know where you can get a quick charge at a local mall while ordering coffee? Nope, it just gets charged over night when you're asleep, no problem.
With respect to your phone analogy, if I weren’t able to charge my phone at home or at work, I would definitely be interested in being able to fast-charge it at some conveniently located business
If you have a wall plug at home, an EV is basically always full. I'm shopping for a flat and one of my non-negotiable requirements is a parking spot with a plug. The one I'm looking at now even has a three-phase plug, which is a nice extra, but not really necessary.
