The Barty Party

Abusing ball boys is hardly a great start to win over the local crowd. 

To be fair, all he did was request that the boys at the end of the court have an equal number of balls each when he was serving - he didn't abuse them.  Medvedev was bemused that they had to run to each other and hand the balls over, not throw them.  But it was another example of a clumsy approach to a simple request.
