Actually, on a similar vein, one thing that annoys me and could be fixed is the colour of the players shirts. It is usually Nike who seem to kit out virtually every player in a tournament in the shirt and shorts a la mode. They are obviously trying to push sales on the latest design, but it seems almost the norm for both players on a court to be wearing the same kit, and it is so annoying - mainly in terms of being able to identify who is who, easily.
Ditto, in the Davis Cup, virtually every team was in red or blue - and often two red coloured teams would play each other. If Canada play Serbia or Spain play Japan, or whatever, USA versus France ,can we not have one of the teams wear a different colour!!!
