well I am going to probably be mocked for this but luckily we are all entitled to our opinion. At Phillip Island a few years ago, my brother and nephew saw Lorenzo and my nephew who was a huge fan of Lorenzo (he was 8 at the time) yelled out excitedly as a kid does and went to run to him and before my brother could step in and grab him, security blocked him. Which wasnt a problem as that what security is there for, but when my nephew asked for a autograph Lorenzo just stared and said something in Spanish to one of the people he was with and then walked off with security and the people he was with.
I dont think he's arrogant or self entitled as i dont even know him - and i also get it would be quite exhausting constantly having fans mob him. however when you have an 8 year old boy in a lorenzo shirt asking for an autograph - sure, you dont have to give one but he could of at least acknowledged him with a smile instead of a death stare and then ignore him.
and yes - im sure Rossi and many other riders have done similar but for me personally, I just dont like Lorenzo after that because of how upset my nephew was. Yes kids are annoying at times and I know my nephew was in the wrong but still I found it harsh. And that's just my opinion and how I feel
