Anon spends all of his bits on Berry Punch's Alcoholic Punch and is pushed by Twilight into finding a job. Starlight suggests that he works with Trixie as an assistant for her magic practice. Anon believes this should be easy enough and agrees. After practice Trixie demands praise and Anon gives her scritches. Then Twilight asks for scritches and she gets scricthes, and this upsets Trixie.
By all means this description does not mean this story has a plot, or can even be considered a story. I'm not sure if that makes this a spoiler or not, but I'll mark it as one just to be safe.
Kind of like a prequel to Anon Gets a Job at Ponyville Spa, but I'd be a liar if I called it that.
