A$AP Rocky is serious about his fashion wares. The always dapper rapper abruptly ended his concert in Germany on June 6 after a fan allegedly took his one-of-kind Supreme hat.

In a YouTube video (spotted by PopCrush), A$AP Ferg was performing his 'Work (Remix)' when someone in the crowd snatched Rocky's hat. The Harlem rapper grabbed the mic and demanded the thief return his rare cap to him, no questions asked.

“Who took my s---?” he asked the crowd. “I came to party with y’all, give me my hat so I can [continue]. That’s a one-of-a-kind hat!”

“We ain’t gonna f--- you up, just give me my s--- back,” he pleaded.

After a few minutes of waiting and debating, Pretty Flacko and his A$AP Mob crew exited the stage, much to the disappointment of concertgoers.

"Nobody know nothin,' huh? Germany, it’s been good. Thank you; I’m out this bitch. Peace!" yelled Rocky.

And with that, A$AP Rocky left the building.

Rocky loves Supreme clothing, so it's not shocking that he holds the brand in high regard. It's unfortunate that an eager fan had to ruin the show by taking his cap.

Yes, it was only a hat, but what occurred here was a crime -- theft by a fan -- and that's not cool. On the flip side, ending a show over a clothing item isn't swag either.
