The "Yellow" singer was caught on camera snapping at aggressive autograph hunters chasing him down for a scribble following a charity gig.
Chastising the men for their tactics in video obtained by TMZ, the 42-year-old said: "(Treat me) as a human being. Don't shout at me, it's so aggressive. Either ask nicely or just f**king be polite."
"Treat humans with decency."
Explaining he might have "family s**t" going on as they demand his attention, Martin makes it clear he knows the men are not real fans, adding, "These (signed items) are all going on f**king (auction website) eBay."
He then suggested his bad mood had something to do with "a shitty gig", adding, "which I did have".
Martin had just left a concert for prison reform in Los Angeles on Monday night (January 20) when he met the autograph hunters.
