That gets on my nerves too. I played in a tournament today, and I generally would wait by my bag or on the edge of the green for the others to finish, and the guys I was playing with did the same. But I’ve had people do that before. I’ve had people walk to the next tee after they’ve putted out, leaving me on the last green alone. Occasionally one or more of the others in my group will have teed off by the time I get to the tee. It ticks me off.
Was this your first Aimpoint lesson? I’ve been curious about it for quite some time. I use my feet heavily to read greens (and have become a significantly better putter since learning to do so) so adding a bit of methodology behind that makes a lot of sense.
