It's OK if we have different opinions. I watched Fabio live in Toronto and he was a petulant child. The crowd became so disappointed with his attitude that they started to boo him. I hadn't seen that before. He slammed a ball at a lines kid. He yelled at the ump. He berated the crowd. He delayed the match by being super slow walking back on court or facing the server. (And I've seen it since on TV.)
He was just like Nick. (OK, not quite as bad.)
Of course I love that he has a great life away from the courts, but that doesn't mean that he is 'professional' and well balanced on court. That is what I was referring to. Just my observation. I'm sorry if it doesn't match with yours.
We all have different experiences in life.
