I had the same thing happen to me. Felt sorry for a guy I had just met because he had been hunting elk for years and never tagged one. My buddy and I took him to one of our honey holes, and as luck would have it...he tagged a raghorn bull. He left for home (out of state) happy as all get out. My buddy and I were happy that we helped the guy out.
Untill the next year, when he showed up ahead of us and set-up his camp in our spot...with a huge wall tent and 5 of his friends!
NEVER again, that's for sure & for certain.
