[Meta] Searching for a Story about a human mechanic and his... unique language

Hello together.

Recently, I got reminded of a (possibly one-shot) story about a human mechanic that I read years ago. Sadly I can´t find it. Perhaps someone remembers it?

What I remember: The human worked on a space station and some aliens came up to him. They wanted him to repair their ship. The human spoke only with "fuck" and its variations like "Fuck?" meaning "Hello, How can I help you?" or "Fuuuck... Fucking fuck's fucked", meaning "XYZ is damaged beyond repair and needs to be replaced". Perhaps he replied to the question "How much will it cost" with "Ssssh... fuuck...", meaning "much". He also had a female alien companion / translator who dilligently translated what he said to the aliens. I distinctly remember that the end was that the companion asked the human what he would like to do now. His answer was: "Fuck?"

NSFW tag for language, just to be sure
