How does Harry get gas?
Every gas pump, other than the rare vintage, has alot of electronics in it. And Harry drives all over the place with the Beetle and other cars. With a 60s Beetle getting around 20 mpg city and having a 10 gallon tank, he has to be filling up pretty often.
When he goes on Larry Fowler with Mort, it's shown he has a (at the time) new "spell" that helps him contain some of the "Murphy-onic field" that he emits but how did he do it before that? And we never see him use that technique again. My hunches are: he parks at the farthest pump and hopes for the best, Mechanic Mike has a pump on site and fills it for him (rare in all but the biggest shops but you never know), or he has an arrangement with friends to fill up for him.
This is a really particular and small thing that I haven't been able to get out of my head lately so I figured I'd see what the broader community thinks. I don't think Butcher needs to add this to a story, I'm just a huge Dresden nerd and really curious about the small stuff 😅
