I call out whenever I see any other cyclist stopped. Most of the time they are all under control but sometimes they appreciate help. It's usually a case of needing my frame pump. It's surprising how may times I, or we on the tandem, have helped someone. I shouldn't talk - one time I swapped bikes just before commuting and forgot to transfer over my pump. Wouldn't you know, I had a flat that day. Another commuter going the opposite direct and with whom I've been exchanging waves for months came across the road and helped out.
