Is there anything more annoying than playing behind a group that will not let you play through? Even worse, you are 2 or 3 holes behind them and there's no way to catch them to go through. I've been so frustrated at times I've actually said "screw it" and gone to the house. I've even quit and waited for them to finish so I could educate them on proper etiquette but it doesn't seem to sink in 'cause I see them doing the same thing all over again later. There never seems to be a marshall or ranger around when you need one.
