I guess it depends on what you told him to do. I'd say 95% of the time, that's an EJ.
Putting on a uniform doesn't automatically get you respect. You have to earn it. If some knucklehead is saying "you don't tell me what to do!", you don't have their respect. Yet.
I teach the classic "That's enough!" with the hand up, from a distance, and "That'll do" for up close conversations. It works for the four foot nothin' 12 year olds I have working 9-11 year old games.
Respect starts when you walk on the field. If you have no reputation, it starts with your uniform. If you look sharp, the old saying goes you'll cruise by the first three innings. Dress like a slob, and they'll be on you right away.
Lots of managers like find your limits by pushing your buttons. "COME ON!", "HOW IS THAT A STRIKE!?" etc. That's when "That's enough" needs to be employed early enough to set the tone.
What's really key is have your Umpire in Chief set the tone for the league. They have let the managers know what is, and what isn't acceptable, and the consequences for stepping over the line. He also needs to let them know that umpires are umpires, no matter the size or age. Everyone needs to be on the same page.
