No, club gliding means for the majority of pilots flying club aircraft, much like SEP flying I imagine (I may of course be wrong). Glider owners actually tend to be quite good at taking their share of duties. Because they usually want a hand rigging their gliders...Gliding clubs are all self help, there's a rota for winch driving/aerotowing, cable retrieve, duty pilot, duty this that and the other. Some people think that rotas are for other members though and they can just turn up, fly and go home. Every gliding club has them. Most members of most clubs accept this, although not gladly of course. I, having more of a sense of right and wrong and of people taking the p*** and being a well built chap who used to box, tended to tell them what I thought.....
The strangest thing was that other members who would mumble into their beer at the clubhouse complaining quietly never liked it if I gave friendly and much needed advice to people. You can't please some folk.
