I don't think you can blame the referee, he gave it as he saw, a penalty. However once the decision has been made he's not going to change his mind. Yes you can protest and as a captain you have the right to question a bit more for an explanation. WG had two goes questioning the referee before the penalty was taken, in fact he also attempted to delay the penalty by walking up the taker and then taking his time to leave the box. At this stage the incident should have been over, decision made, protect made and won't change the decision.
After the penalty he had another go at questioning the referee by running to him, mostly now out of frustration due to a goal being conceded. A booking was justified by his reactions, whether you agree with the penalty decision or not. Again not happy and he, WG sounded off again and seemed to get a straight red.
