You're not going to make any friends like that bro.
Most syndis and clubs are the same. The longer term members can become very protective of the water which is completely normal, and this can very much give the impression of a clique. It is human nature to an extent.
You have two options in this case:
1 - Take the defensive, kiss my ass attitude. This will set you up for a campaign of animosity.
2 - Feel your way in, gently gently. Be on your best behaviour, show respect and etiquette (which in the long term you WILL be shown in return), get to know the members and become part of the group. End up with a bunch of new mates and the camaraderie associated with any decent syndi or club.
Worry about your own results, not others mate. Being done 4 times and losing one, when "no one else had nothing" is nothing to shout about imo bro.
Even if you had caught 5 there's no need to compare your results to others just to big yourself up.
There is a fine line between commenting on the high and mighty attitude of others and exhibiting that exact same characteristics yourself. Relax and enjoy your new water bro. Those other guys are only human, you'll probs get on like a house on fire in the long run.
