My first ever game was a vets match where the away team were all very vocal in challenging each and every decision made. At one stage, one of the away side came up to me, looked at me, then looked at the Ref badge on my shirt and then looked back at me quizzically. Clearly, he was silently suggesting the fact that I was a qualified ref. In your opinion, is this enough in itself to warrant a yellow for dissent (by word or action)? - I didn't show a card at the time but in retrospect belive that I probably should have?
