Adrian Mannarino

What a total f@cking c@nt.

Strong words. 

What happened?

As he went to sit down at end of game he shoulder barged a ballboy. It is up on the BBC website.

Molehill - mountain.  Mannarino was just walking back to his chair, looking tired and a bit dazed, and then the ballboy was in his path.  He wasn't expecting it and looked surprised.  The ballboy looked fine - it was a low speed collision.  Usually the ballboys don't get into the path of a player when the player is walking back to his chair - especially when the player is walking between the narrow space between the umpires chair and the net.  If I was the ballboy and see a player returning to his chair - I would allow the player to pass rather than to get into his path.  With time violation penalties in place, the player cannot be expected to be negotiating an obstacle course of ballboys and ballgirls everytime he is returning to his chair and trying to catch his breath.

Doesn't look intentional or remotely disrespectful to me. I think he was just distracted, lost in thought as he walked to his chair. I'm not aware of any history of poor behaviour, unless others know different (?)

A quick apology, prompted by the Umpire, would have been sufficient. Point penalty rather excessive.

He wasn't looking and bumped into him

If you look at Mannarino's reaction in the split second after the collision, it looks like he wasn't expecting the collision. I think it was vey likely an accident.

Either he wasn't looking, or, he just assumed that the ball boy would scurry out of the way like the good minions they're supposed to be.

However, he didn't help himself with his silly excuses. Maybe he was right, and maybe he was wrong, but better to take responsibility, especially when you are the adult and they are the child. If someone comes out of nowhere and you don't notice them until the moment of impact, it's usually at least partly your own fault. Although they are probably both at fault. I imagine the ball boy will have something to learn from this as well.

A minor incident though, I agree with that.

Any decent person who walks into someone considerably smaller that them (even were it an accident) would apologise imeadiately not give a scathing look as if to say how dare you get in my way and then come out with some pony about it being caused by a hip injury.

What a pr!ck.

Maybe near in mind that he was in the middle of a battle and exhausted 

Not everyone has that British oh I'm so sorry attitude. He was more annoyed he got penalised. Rather than annoyed at the kid

I neither know nor care whether it's a British attitude, more that it's a decent person attitude. His comments about who is more important kind of sum up the sort of person he must be.

Hey ho if others don't agree but would it have taken anything much for him to apologise afterwards?

Golfers who accidentally hit a member of the crowd with a ball make a point of apologising imeadiately afterwards as a rule.
