I’ve seen my own code appear with someone else’s name on it, sort of flattered and a little pissed off at the same time. Internal performance measuring software.
In my teens, I worked at a petrol station that had a car wash. Seen a nice sports car (well think it was an MG), get a new go faster stripe, perfectly front to back, over the top, from his Ariel or a previous user’s.
It’s actually quite palatable, I had to try it, well because it’s Japan. That and a litre can of Kirin from a vending machine used to cheer me up for some reason.
