I know of one big owner down Warrnambool way that won't put him on because he won't ride to instructions I don't like me either has slaughtered plenty of mine over the years good luck with him.
But I will say that's good that he says hello to staff/punter's I have seen first hand behaviour of jockeys and some trainers where they think they are rock stars and treat people like sheet because they don't know who they are.
