I recently played 9 holes of golf at the Highlands Golf Club. I shelled out $15 in ones for the cashier. "Tip money," I assured him. I did not elaborate.
I'm an average golfer. Sort of a weekend warrior on the links. They say it takes about 10,000 hours to get good at something. With this measurement, I'm about a quarter of the way to golf mastery. But you wouldn't know by watching my swing.
