I guess we'll have to agree to disagree. It's extremely rare that your partner needs to know why a sanction was requested (with the exception of a protestable error), so if you have any level of trust in your partner's skill, there's no need to know exactly why a sanction was requested. If a coach needs to know, then the captain can tell the coach. If the R2 happens to be there when the coach hears, fine, but if not, the R2 should be making sure the scorer records the sanction and the coach can send the captain for more explanation or ask the R2 at that point.

I've had a handful of times when my R1 has requested a card, and the coach asks me, and I've always said, "Send your captain to ask." And yeah, I've been curious myself, but the coach is already at the attack line talking to me so when the captain comes back, I can easily hear. If the conversation has been further down, I've never been concerned enough to feel like I had to hear it, because I didn't need to know the reason.

But your mileage may vary.
