A few years back, I had a CYO coach that told my partner and me he also officiated. I was largely indifferent over the revelation. In a different game I officiated with his team later that year, I had to wonder about his training when I called what turned out to the 5th foul on one of his players and he insisted I couldn't call a PC foul on his player because the defender was under the basket.
On the other side of this perspective, I've captained an adult kickball team in one of our area's social clubs in recent years. Should I need to approach the umpire about a rule issue or concern, I do everything I can to avoid mentioning that I'm also state-registered in softball and I try to treat the umpire as I'd want to be treated should a coach/captain have a question or concern to address with me when I'm officiating a game. I'd rather not become the discussion topic of one of these posts if I can help it.
