In a video on TMZ, the Coldplay frontman went off on a group of autograph seekers hounding him after a charity performance in L.A. on Monday night.

“Don’t f**king shout at me. It’s so aggressive…either ask nicely, or just f**king be polite. Treat humans with decency,” he said in the video. “These are all going on f**king eBay. I always sign at least one each!”

He added, “I might have family s**t or a s***ty gig, which I did have.”

Martin did end up signing some merch, though, before walking away.
