My life's not exciting enough for me to have any cocaine, let alone severed human fingers (which I'd store in the freezer if I did that sort of thing). Mostly soap scum and mildew and hard water stains. Guy is just an unprofessional asshole. Didn't even fix the drip in my sink!
Whoever thought of the term "Diesel Punk" was just someone extrapolating from "Steam Punk" and reasoning that since people in the 30's and 40's used diesel engines, that would be a good way to designate this subgenre-- never mind that the characters in 1930's Pulp SF used Atomic energy. Maybe better to say it's set in a Retro Art Deco Buck Rogers universe.
