You will find most people are generally quite helpful, and most people realise its the newbies which will keep the sport/hobby going into the future.
However I know sometimes it can be a little pain when there are new guys wanting to fly and ask questions when in fact you just want to fly yourself, but I never will go to the extent which you said below, and do my best to help them out. The last thing most clubs probably want is to not have newbies comming into the sport/hobby.

Cheers,
