Did you start this thread BB, after learning of an extraordinary attack by Tomic who unloaded on Hewitt after first round loos at his presser?

Your intro video shows only examples of on court disrespect. I'll add to it some off court examples, that are more telling, because off court examples are committed with premeditation rather than "in the heat of the moment". The player had time to debrief his match and form his long term opinion of the situation he's in and carefully tell said opinion at the presser. The #1 king of all disrespect not only in tennis but arguably all sports, is of course Tomic. Couple years ago after having lost in Wimby, he unloaded on Pat Rafter (then DC captain), because the keepers of Pat Rafter Area in Brisbane denied Tomic free access to the court. Tomic thought he deserved free access so became angry when they stopped him and asked him to pay some $20. This incident is also an indication of Tomic's stupidity, because if he disagree with the rules of Arena hire, he should argue with the rules but he went after the Arena's name and thought Rafter was hie enemy. Then he went after the whole Tennis Australia, including Craig Tiley.
It looks as everyone around Tomic doomed to become his enemy, so Hewitt was next in line after Rafter as DC cap, and even the innocent reporters who just ask the questions. Take a look at the extraordinarily disrespectful body language of Tomic captured by the video of my The Age article. Notably, at 1:00, when he turns sideways while talking to the reporters. I've never seen such extraordinarily disrespectful behaviour at a presser before.
Kyrgios largely grew out of his on court antics shown in your video but Tomic did not. Worse: Tomic displays the same disrespect both on & off court.
EDIT: I use the pronoun "he" while talking about tennis players here because all examples of big disrespect always come from male players. There are hardly any comparable examples in women's tennis. Serena stands out as the biggest case women's disrespect on court but off court she's always nice and well composed. And there is no way to draw any parallelism between Serena & Tomic behaviours. While Serena may have some personality issues she needs to work on, Tomic is simply a disrespectful psychopath, IMO beyond any help, and he's going to stay and die like that.
