I've just remembered another one! First time I played Aldenham, we finished the par 5 9th and looked around for the next tee, turned right and there was one just behind the bushes. Saw 10 on the tee marker so we all teed off. Then I looked at my GPS and it said we were miles away from the correct fairway. It turns out we'd just teed off the 1st of the accompanying nine holer. The tee marker had actually said 1/10 in case you want to go round it twice, haha. We should have turned left after the 9th green, but the sign pointing to next tee had been knocked over face down.
