Do TPKs happen at your table?

My group TPKs about once per three one shots, but pretty much never during actual adventures. I remember only once, during the final boss fight. It was set up as holding on as long as possible and succeeded, but we were actually trying to survive.

I'm OK with TPKs and PC death in general, but prefer it only if we decide to do so in a blaze of glory or whatever. TPKs because of stupidity on our part is fine but less fun, TPKs for reasons beyond our control isn't fun at all.
