Two years ago, I was at Patriots Point in Charleston as a single and I was partnered with a threesome. First hole went pretty smoothly but the threesome was obviously playing for money. Teeing off on the 3rd hole, one guy hits his tee shot well into a water hazard. He says it’s dry, he saw it land, buddies said “just hit a provisional and take the stroke if you can’t find it”. Instead, he drives out 250 yards and starts looking. After 5 minutes, he says he’s taking a mulligan and drives back to the tee, while the next foursome is waiting to tee off. Then the other two start in with similar antics. One tosses his ball from OB, and the other starts arguing about the others not counting their strokes accurately. Their literally arguing on the green while the group behind us is waiting. I finally got fed up after the 12th hole and told them I had to leave. I skipped to the next hole, which was open and played the rest of the round as as single. I get back to the clubhouse and said something to the ranger and he said, what can he do, they paid their greens fees. Probably the worst behavior I’ve ever seen on the course.
