> There's also a relatively common experience I've heard where people who aren't actively suicidal call these lines, and the operator (I won't say counselor) is completely dismissive: "if you're not going to hurt yourself, what do you want me to do?"

That would get you dismissed from any reasonably-run suicide hotline program ASAP.

I have a friend who volunteers for a suicide hotline program here in the US. He says it's actually well run and they keep close tabs on the volunteers. Everyone who volunteers is doing it because they care. It wouldn't make sense for someone to volunteer for such a program just to be dismissive and rude to people who call in. However, I could see this happening at poorly-managed programs that use low-paid employees without proper training and supervision.
