Luhan was filmed yelling at a taxi driver.
A video surfaced filmed (by a sasaeng fan). A taxi driver had been taking the sasaeng fans around and following Luhan during his movie filming, and Luhan, very understandably angry, yelled at the taxi driver, saying, "Leave" multiple times.
To make matters worse, the taxi driver yells back, "I'm not going to leave", making Luhan get even angrier. He was dragged back by staff, but the video was uploaded onto YouTube. You can see the video above.
