Had a run in with a hot head today. Hit my drive with a big slice to the right, heading onto the opposite fairway. Group walking up that towards us so I belted out a shout of fore. Literally couldn't have shouted loud enough, they were too busy gabbing away and my ball missed them by inches. Guy comes screaming over, shouting and swearing away pointing his finger claiming I could have broke his leg. Completely out of order, first words out my mouth we're sorry about that, but I did shout. Guy was having none of it though. Really pissed me off, want to make a complaint to the club secretary but never done something like that before, not normally one to complain but the guys attitude was horrendous and I'd hate for him to get away with it and do it again. Any advice on how to handle it?
