Poor Liam Payne.
If this Vine is anything to go by, he was not having a good time taking selfies with the fans. But the One Directioner clearly has a lot of practice with it. He's like a machine working that line - fake smile on, take photo, fake smile off, move down.
Well, at least, he's stopping to take photos with the fans and mustering up the energy to smile for the camera.
We're sure they appreciate it. Even if he looks like he'd rather be doing literally ANYTHING else.
