It's a common complaint of surfers that we can take off further inside than they can. So be a bit considerate and only take your fair share of waves. Snaking is a big no no. Snaking is where you paddle in behind someone in order to make it look like you took off inside of them.
Local riders tend to get the set waves.
If you treat others with respect, they will treat you with respect. Learn to be tolerant of others dropping in. If it persists then you're best off surfing somewhere else with a decent crew. And remember when you're paddling out, anyone on the wave has right of way so stay out of their way. As we all know, there is nothing worse than catching a wave and having to dodge the crowds on the way in.
