I don't know about you, but I am more worried about getting my tail to the next match I am coaching, rather than asking a ref who he is. Especially one that I had a disagreement with. What do you think he is thinking? Wanting to look up his address so I can teepee his house? You know what happens when you tell a ref you don't like him.

"Hey ref that I just debated why it took you 3 seconds to get down on the mat and start the backpoints count, would you mind me asking your name, I'd like to send you a Christmas card"

I'll take it a step further. Make coaches where name badges also. If the refs would like to know who we are, that is fine with me.
