I'll start off by noting my age -- 16. Because of that, I feel like I take more heat than older umpires.
Last night there was a close play at first base -- I called the runner safe, and I was entirely confident with my call. Coach comes out and asks for me to ask PU for help because he "had a much better angle than you." I said "she was safe" probably 3 or 4 times, because as I said, I was pretty much positive I got it right. Coach keeps asking, and I say "that's enough" while turning my back to him, which he responds with a "no, that's not enough" and follows me. I say "alright, please go back to your dugout" and he does, but while loudly saying "that's BS, that's BS" (no, not swearing).
I chose not to restrict/eject because 1) I didn't feel he crossed the line enough (though if he kept going I would've restricted) and 2) he wasn't swearing. But I am not sure if I should've restricted for this.
Can I have some tips on how to better handle situations like these, especially because I'm already disadvantaged because of my age?
Thanks!
