Had to caution a player for delaying restart. He was querying why he was being cautioned which I obviously explained and asked for his name.’Jack’ he says and walks away. He then refused to come back to give me the rest of his name! At this point, his coach shouted that he would remove him and that seemed like an ok outcome. However, I am questioning whether I should have insisted on giving him a dissent yellow and sin bin (I recognise that this is the lotg here). There were only a couple of mins left at this point and my thinking was that insisting on the letter of the law would possibly inflame things rather than calm them. No complaints from the opposition btw.
