It's no secret that there are people out there who try to get artists' autographs for the sole purpose of selling them. It's why so many artists refuse to sign stuff anymore.
Well, Shawn Mendes has had ENOUGH. This dude was trying to get a bunch of stuff signed "for his sister". Needless to say, Shawn didn't really believe him - and the man's hesitation to call his sister made it even worse.
Warning: Shawn uses some NSFW language in the video
Eventually, Shawn ended up signing the merchandise, but not before telling the guy what he thought of him.
The fact that Shawn wants to make sure that autographs are special for his fans makes us like him THAT MUCH MORE!!
