Sometimes I’m at the doctor’s office, at the library, or even at the grocery store and see an unused power outlet. My phone is dying. I feel weird plugging in, but I feel even weirder asking for permission.

Phones charging use such little power I’d really be surprised if anyone cared. It really depends on the place. A library I would have no issue plugging in anything without asking. I can’t say I’ve ever been at the doctors and considered charging my phone though I may ask out of courtesy if I did simply because I like my doctor. Overall I’d say it wouldn’t be a big deal either way.
They use a few cents (in US dollars) a year.
A 2000 mAh battery that is charging at 3.7V for one hour per day uses 2.5kWh of energy per year. About $.50 at ~$.20/kWh. That’s pretty remarkable!
