Tennis fans need etiquette lessons

The Olympics is not the first time Beijing has staged a major tennis event, but it seems Chinese spectators are yet to grasp the finer points of the game's etiquette.

Fans can often be heard cheering at inappropriate times, such as in the middle of a rally or when a first serve hits the net, and many more seem to think it is fine to chat loudly on their mobile phones while a match is in progress.

But whether or not this ebullience is off-putting for the players is a matter of opinion.
