I tried something similar...

I do my dev and printing in shared darkroom place and I had wound the film, put it in the tank and was ready to go. While I was diluting the Hot Rod, another guy grabbed my tank thinking it was his...and filled it with...FIXER!!!
After 15 sec of fixing I pulled the tank out of his hands and emptied it...washed a lot and tried to develop it....VERY THIN NEGS!

That day I became a murderer!
