I was at my local range today and was working diligently on a new swing. About half way through my 100 ball bucket, I overheard two guys talking rather loudly as they approached an open spot behind me. As I transitioned from my 7 iron (hitting the ball rather cleanly and consistently with this iron) to my 3 iron (my former go to club off the tee, but now struggling since changing my swing) I overheard what seemed to be the instructor telling the pupil he was crushing the ball out to 250 yards!
I am 5'10, 230 pounds and athletically built in my early 30's, and not even I can hit the ball 250! This other guy, was probably mid-40's, very overweight, and not athletic in build by any means.
As I cleaned my clubs, they continued their banter as the pupil struggled with even striking the ball, while the "instructor" was essentially lying to the guy.
I am familiar with golf course etiquette, but what is the proper thing to do in this situation? I feel bad for the guy, because I imagine he is paying for the time and instruction from the instructor. However, walking up to him in the middle of a lesson would certainly make the instructor mad. If I see the guy again, what should I do? Should I encourage him to look for another instructor? I am new to the area so I don't even know of a good instructor.
(By the way, I am changing my swing off of some solid advice from a guy at a different range that is bordering on trying to enter the professional golf arena. I didn't pay anyone for the tips on changing my swing, so I don't have a way of helping the guy out at present.)
