None of them as they make themselves look like absolute cowards by quitting.
To me, quitting is more humiliating than being evicted and booed really loudly.
I'd rather be evicted to a booing crowd than ruin my career and take away my dignity by quitting and looking like a coward.
It's a shame because those walkers now have the "CBB QUITTER" tag for life and that is beyond embarrassing.
