When I used to golf (VERY infrequently) I noticed that my terrible game improved modestly when I got a couple of drinks in me - then if I ventured a couple of sips more past the sweet spot it quickly dropped off the cliff. I suppose relaxed is a good thing but too relaxed is another story.
Back in my young days, mid 20s, I was at the golf course and knew the manager decently. I had a whiskey/coke, acutally had a couple of them. Told the manager I was going to go walk 9, he said he would top off my drink and went straight jack daniels. By hole 4 I was seeing 2 golf balls and just quit, the swinging between them wasn't the best. Went in and ate supper, hung out a enough to be legal again and went home.
