When I Were A Lad.....
My first proper job was working at a airport where they serviced DC3's.
Quite a few of the staff used to suppliment their petrol bill by siphoning off a gallon or three of AVGas (including one foreman known as "Hovis" who was found in the act by a colleague at 3am after returning a late night run of taking urgent parts to Birmingham EM).
One other young lad decided to run his little moped on it full time draining fuel from a couple of DC'3s parked outside, those of us on 2 wheels used them as covered parking space (Something like a Honda Sky 50), completely knackered his engine.
I dont think he ran his new machine on it after that
