We have a par 3, there is a cart/path running down the left hand side of the hole. The tee shot lands on the fairway on the left hand side of the path, a few inches from the side of the path (gravel path, no concrete). For a right handed player, play it where it lies, no problem.
For a left handed player, they have to stand on the path to address/play the ball. The left hander thinks they should be entitled to a drop (so that they are standing on the fairway rather than the path).
I couldn't see a problem with playing the ball as it lies. The ball was lying on the grass, there weren't any other obstructions, just the fact that the player was standing on the path.
Anyway, my view is that there shouldn't be any relief.
