I had a school game today and I ended the game after the ball went out of play for a corner. The game was 30 mins per half, and it was about 33 mins gone in the second half and there was only 1 minute of stoppage/injury time to play. After the that the ball stayed in, and in position of team 'A' so I decided to give them the final attack etc. They were losing 2-1 however that was not the point (to let them score). So when the ball finally went out I blew for full time. Their manager came on demanding that they take the corner and that it was against the 'rules' that I should blow whilst they were 'on the attack'. I explained I had already given them more time than I should of. Who was right? Me or the manager?
