Guess what? Celebrities are people too. They don't have to be constantly 'on' and are allowed to live a normal life. You have no clue what day he was having nor how he was feeling and then you popped up, mentioned his name and pretended like you're his mate. Not everyone is a people person and I'd imagine even if you were the nicest celebrity in the world, having people come up to you and not just leave you in peace would get grating after a while. Why did you feel the need to go up to him and try and start a conversation if he's just shopping in JD? If the guy wanted to be left alone then he wanted to be left alone and because we know his roots he's probably not in the mindset for being polite when telling people to leave him alone so no wonder he said 'feck off'. Leave the guy be. There's plenty of stories, endless amounts in fact of celebrities being 'rude' to people when the reality is they just want to be left alone to do their shopping and other menial tasks like everyone else. 'Fans' get wound up that they weren't absolutely wonderful people that wanted to know everything about them and invite them for a pint and become best friends so they call them arseholes or say they've got a screw loose because their expectations (as you said, your eyes 'lit up' when you saw him) didn't match what happened when you approached them. That's a copypasta, I've read that a bunch of times about different celebrities, most recently James Maddison. Are you a bot or are you just copy and pasting?
