The 25-year-old actor said he has developed a confrontational method of deterring fans when he wants time for himself, reported Daily Express.
"I'm quite sensitive to people. You pick up on moods quicker, I think. I'm also really good at sensing if someone is around. It's weird, it's like a sixth sense.
"I always know if someone's taking a picture as well... You see people just taking a picture casually at a different (restaurant) table. I've got into the habit now of going up to people with my phone with the flash on and just start taking pictures two inches away from their face," he said.
