I'm just going to throw this out there.
There is zero reason to be rude to your fellow players. If someone shows up and announces they have never done the FP before but read up on it a bit, I have zero problems taking a couple seconds to explain mechanics.
On the flip side, I get very frustrated with people that announce they have never done the FP before, and that they didn't bother reading up on any of the mechanics so they have the slightest idea of what is going on. That is perfectly ok if you are playing a single player game and are just wasting your own time dying over and over. But when your lack of preparedness affects four other player's time, and their pocket books in the form of death repairs that isn't ok.
