When Simon (Iwan Rheon) is in the bar scene, he has green and white stripped shirt. After Kelly (Lauren Socha) leaves he has on a solid green shirt on until they leave the club. He goes back to wearing a green stripped shirt.
When Curtis takes out his jacket to help Kelly for the second time in the episode, he first takes out the money from his pocket and he then bites them, in order to free his hands. The money changes orientation, as the folded part is first looking towards his mouth, then towards the camera!
