Pete Consoli at Springdale GC in Princeton, NJ.
I was a caddy there in the mid-70's and he was the caddy master. A prolific ball striker and PGA tour wash-out, Pete had the game but just not the temperment. Since I played so much hockey as a "lefty", I naturally started playing golf from the left side.
Every Monday, since we were not members, I would play on "caddy day". Was on the range one day and noticed that Pete was watching me. He walked over...
"Mackenzie, what the F are you doing?"
"Uh...hitting balls..."
"Youre an idiot, get over here."
He hands me a right-handed 7 iron he was carrying.
"Here", he said, "Hit this."
"uh, Pete, It's a righty club."
"Well arent you observant today."
He then gives me 3 pointers on grip, posture and stance.
"There you go. Play from the right side now."
Pete went on to become head pro at Springdale (William Flynn) and honorary member.
I'm a righty and a loosely "competitive amateur" player at a +1 today.
Thanks, Pete.
A follow-on to this anecdote was that Pete and his assistant (a Scot from St. Andrews whose name I forget - Bill Crane, help please...?) gave me a set of right handed clubs and charged me $5/week until I paid them off.
A 1-3-4 wood set up if Dunlop Maxfli woods.
Full set of MacGregor Ben Hogan irons.
