I can't legally pay for parking in my city.

So I don't. Fines are very low (almost not worth paying, entirely), so I don't sweat it (and know where lots of "free" parking is).

Definitely this makes scheduling important – and then following through. I will typically arrive a bit early, and not leave until (they're) fifteen minutes late.

It is cumbersome but worthwhile; if I had family (or was "on call") this would obviously be impossible.
