Still a reply is in order.
We as fans get annoyed waiting for these guys to go through all their "routines" or OCD issues. It slows down the game to the point of being a waste of time for all but the fanatics who support their player. Furthermore, if they are routines, why didn't a parent or coach get them out of the habit years ago
Did they think they were so fragile mentally that any alteration in their quirks would unravel them? Nadal's mother should be aghast that he picks his butt in front of millions of people, so why didn't she tell him to stop?
As to Novak and his intermittent 20 ball bounces, the chair umpire should invoke the rules and put a stop to his nonsense. Between these two alone you have rules violations every single game. If I were playing against them I'd ask the chair do something or demand the tournament director have the chair enforce the rules.
