It's not easy to hit a golf ball several hundred yards and have it land neatly in a cup 4.25 inches in diameter. But, sadly, some golfers do experience this problem.
Yes, that's right: hitting a hole-in-one can be a bad thing.
That's because in some golfing cultures, particularly Japan the the UK, golfers who sink a ball in one shot are expected to throw a party. They should, at minimum, treat everyone in their group to drinks back at the clubhouse. In more extreme cases, social standards compel successful golfers to host lavish celebrations costing thousands of dollars.
That's why some golfers purchase insurance to protect themselves from an unfortunate hole-in-one. Alex Mayyasi writes for Priceconomics:
