Many years on rock and ice.
My guess is that a majority tend left.
An erstwhile partner was a climbing bum named Mark Udall.
I have met a few ‘tourist climbers’ that had notched Everest; always megabucks, others were the paid help.
Once found an unopened bottle of rum in the snow at over 14k!
Yes, we packed the empty out.
Great story about the (unopened) bottle. One can just imagine the gasping newbies desperate to shed weight. I have a good deal of experience in high country hiking and scrambling in USA, Mexico, and Switzerland — up to about 13,000 ft — but never any technical routes.
