I've been given a free caddie twice, but, I paid them anyway, also. As a former caddie, you can't have a big enough day. It makes up for all the stiffs that play this game.
I've been fed, but only as part of an organized retreat, which I pay to attend.
I've played with the pro on a couple of occasions.
If this post is in somehow meant to impugn anyone's character, implying that their vote can be bought for any of these things, it's pretty weak.
My favorite story about quid pro quo involves the Donald. A rater is at one of his courses. On the 5th hole, he and the caddy are on the tee when who should come zipping up in a cart? Yup, The Donald. He says to the rater, "I need a good rating, what can I do for you?" The rater says "Excuse me?" He repeats " I need a good rating, what can I do for you?" The rater thinks for a moment and says,"How about a picture?" The Donald thinks for a second and says Ok and begins to fix his hair. The rater hands him the camera.
