I have never been ejected and only once restricted to the dugout ... But many years ago while coaching 1st base as an AC I should have been ejected while arguing an obstruction non-call ... I was right but going about it the wrong way ... The HC came over to calm me down just as the Umpire finally had heard enough ... He spun around to point at me and give me my well deserved ejection just as the HC stepped in between us ... He got slapped with the ejection but never spoke a word.
