It must be a guy thing. I never seen any lady golfer offering advice.
I've seen one guy at the range just ogling my bunker practice. I can feel that he really wants to give me advice but I didn't give him any opening. After a while, he blurted out something like "you need to hit down on the sand." Oh, yeah? At the time, that wasn't my problem. Anyway, I grunted a bit and didn't reply. He kept on watching my practice and finally gave up and left. A few days later, I fix my bunker problem without paying any mind to what he said.
Others won't even wait for an opening and just barge out free instruction to a perfect stranger. And typically, it's something I know already (turn your hip, keep your head down, etc.). If I am in good mood, I will nod with meaningful smile. If I am not, I will just go on without ack'ng his intrusion.
The worst part of it is, some of them are clearly not any better than me. If you are that guy, don't confuse us with your lessons, especially, during a round. There is no magic one liner lesson that can suddenly improve one's golf skill in the middle of a round.
