A Los Angeles artist named Marc Horowitz is already taking credit on Twitter for the Starbucks "parody" store.
As the Hollywood Reporter noted earlier, Horowitz, a conceptual artist, appears to be taking credit on Twitter for the project, which served up free "dumb" coffee to baffled LA residents this weekend.
"my project is causing quite a stir - lol," Horowitz tweeted, linking to a Los Angles Times story on "Dumb Starbucks."
Later, he tweeted, "Would love to do interviews about #dumbstarbucks."
