In a similar vein, I had an instructor slap my hands from the controls and
take over while we taxied up to a parking spot after a check out. We were
going at a slow speed, but he wanted to go to another tie down. There was no
emergency or impending event, he just wanted to go in a different direction.

I explained to him why I thought this was not acceptable for him as an
instructor, and after hearing his weak response, I walked away and never
flew with him again.

He could have said "park over there" or even "I've got the plane", but as a
result, he lost a student and client.
