IN two parts:
I think we all admit that being low hour or low experience at ANYTHING in life means you do have a LOT to learn, but it's hard to learn if no one is willing to help teach you, because it's always easier to sit back and make fun of them and give them crap from a distance with your mates....if someone does something wrong, tell them what they did wrong, how to do it right, and not to do it again
There is too much bagging and not enough helping along in GA;
.......if they do it again, sack them.....you soon learn that way! If they are that unwilling to listen and learn from the advise of someone with far more experience than them, by sacking them you just might save their life
...seen that one work wonders too.
