After 30 minutes of that I told the guy off so his day would be as spoiled as was mine.
I might have tried: "Hello sir. Great day for shooting, huh? You probably don't realize how loud your TC pistol is when you are right next to me. Would you mind moving to a bench farther away? Thank you."
With all due respect to your thesis about how to reciprocate with others in a polite society, I find the majority of people in the real world are usually thoughtless and self-absorbed in themselves, and
they will often become quite indignant by a stranger having the tenacity or nerve to inform them of what they should or shouldn't be doing.....even when said politely with a smile. In your scenario, abnoxious children would behave in a restaurant, and strangers out in public would stop using foul language in front of you and your family, simply via polite request. I suppose the next time this happens at the firing range, I will employ this method of politely trying to explain this to the arriving shooter, rather then suffer another 45 minutes of muzzle brake blast agony and assured anger. But, the chances are good that I will be the one having to pick up and move my stuff away from him, and either way, bad feelings are caused. Wouldn't it be nice if people just thought about others.
