Respect gets respect. If you paddle out and play by the rules, don't drop in on anyone, and let the obvious regulars get their waves, you'll be just fine. If you go out somewhere and aggressively try and chase waves and compete all aggro with the guys who surf that spot every day, you'll be in a little hot water.
I totally get that respect gets respect. I would never show up and go all Brazilian on anyone. I would just be super nervous I would **** up or get beaten for looking at someon wrong.
