I was playing doubles against some friends. When one of them was serving the man that was standing at the net positioned himself at the same side as the server. So when he was serving from the right at 40 - 40 the man at the net was also standing on the right site of the court at the net. Is this legal? I hope it is al little bit clear. PS i had no problems with this (it was just for fun) otherwise i woud have smacked him wright between the eyes hahaha.
