It’s kinda a tricky thing. If playing a casual competition for low stakes, I don’t want to seem like I’m overly paying attention to the other guys’ scores. And sometimes folk miscount - especially if the strokes pile up on a bad hole.
First hole, he drove next to a tree. I saw him pick up his ball and toss it, to be able to swing. When we met on the green, he said something like he “wasn’t going to injure himself or break a club.” I said, “Yeah. I should probably declare unplayable lies more often, and just take the penalty stroke.” So even if he didn’t know the rule, my statement shoulda communicated that there was a penalty stroke. After we holed out, he claimed a score that did not involve a penalty stroke. His score for that hole tied me, so we pushed the skin. Only 50 cents. But the prior 3 holes were also pushes, so it was worth $2. I eventually won all of the pushes on #7 - for a total of $3.50.
In other situations with other friends, I would say, “Are you sure that was a 5?” And count what I remembered as 6 strokes. But I just felt that would be a tad dickish in our casual game. And I wasn’t playing all that well either, so I didn’t want to make it seem like I was being a rules enforcer just to win a couple of bucks.
We generally play somewhat loosely with the rules. If someone loses a ball, we aren’t too careful about exactly where they drop their ball. It is fine for them to give themselves a decent next shot - so long as they are taking a penalty stroke. Hell, we let the oldest guys (in their 80s) tee off from the kids’ tees.
Then on #8, he lost 2 balls. Drive wet, hitting 3 from the tee. 4th shot also wet. Hitting 5 to the green. I wasn’t paying too much attention to his strokes, but I KNOW he didn’t 1-putt, so his score was AT LEAST a 7. He said he had a 6. Same as me, so another push. But my 6 was a freaking double bogey, and I had just won 7 skins on the previous hole, so I didn’t want to seem like I was trying to win ALL the skins, or to rub it in when he had just lost 2 balls on 1 hole.
These weren’t like really unusual interpretations of really technical rules.
