I'm sure most of us come across inappropriate behavior, be it rudeness, dangerous shooting, down right ignorance.
How many people say something????
I'm not a particularily loud or even forward person by nature, but I was taught very early on in my keepering/shooting career that you are not there to be mates with everyone , you are there as a professional and should act accordingly.
It is not nice being in a situation where you know that you are going to cause embarassment to someone or possibly cause a scene but I'd rather embarass than see someone hurt.
If someone is being dangerous , tell them , it might be that with a bit of guideance they are ok as they weren't aware of their actions, they may ignore you,if so tell them to stop shooting or leave [failling that wrap the barrels around there neck] but if everyone tells them to leave they will eventually take the hint or not have the opportunity to shoot.
I think by baptism of fire everyone should at least once be put in charge of 20 italian shooters on a walked up day, you soon become forcefull[or dead].
A lot of people now come into feildsports later in life [which is not a bad thing], not everyone has the chance of being mentored from a young age, starting with a 410 and climbing the ladder with age and experience.
You can't just expect everyone to have the same experience, we have to share and mentor those coming in to the sport/profession. Which is idealy what this site does ,as well as malcs highland trips. Government or legislation can not provide this.
