1994 toyota 4wd 4 runner

I just can't beleive that someone can so cocky just because they work on Toyota and only Toyota evidently. And the nerve of telling other techs and others trying to help to leave this problem alone? I found this as being totally inappropriate. NOBODY will never know everything there is to know about Toyota or any other make. I say he needs to step aside and keep is little attitude to himself. He's a legend in his own mind.
