Never ejected as a player or coach in 35 plus years.
Only two ejections handed out in the past ten years as an umpire. If I had a short fuse or thin skin, or poor game management skills, I'm sure I could have maybe tossed a few more. I do pride myself in being able to handle these situations and end them while still keeping the coach in the game. I don't tolerate bad behavior, but will issue a firm warning if things get out of hand.
And my warnings can be pretty firm! Last year I actually had two different games where a coach ran out on the field to argue a call, I listened for a few seconds and explained the call and they kept arguing about. I said, "Coach, we're done! Get off the field!", (meaning, get off the playing field and back in the dugout so we can continue the game) in my meanest old umpire voice, then turned away and walked back to my position.
Both these guys just assumed they were ejected and actually packed up their things, left the field and headed for the parking lot!
Believe me, if I ever really eject someone everybody is going to know it. They are getting the big, roundhouse, finger point KABOOM ejection that doesn't leave any doubts!
By the way, the two ejections were both players- one for cursing and throwing the bat after a strike out and the other for a runner remaining on her feet on a close play at the plate and throwing an elbow into the catcher.
