Brought to you by the memory of learning about the fuel rats when I first started playing Elite:Dangerous, and then many game hours later having to call on their services when I learned that fuel scoops don't work on some kinds of stars, and was just dead in the water in an empty star system between two inhabited worlds.
And yeah, my experience was just like in the brochure. I honestly wonder if real life emergency responders pick up fuel rat dispatch shifts in their spare time, because wow.
The details are fuzzy, but I remember I was still a mid-level player with a ship whose main asset was affordability and opportunities to amass enough money to get the really nice ships.
I was rescued by an Anaconda, the third most expensive ship in the game according to the wiki. The insurance payment on it alone was more than my entire game net worth at the time. In naval terms, it's like a 300ft superyacht coming to the rescue of a rusty fishing trawler.
