As tigger rightly says, where are the Mucker top brass in all this, that's what I'd like to know? Self policing is the most effective way forward. Punishment for the lobbers could start with a withering glare from Blood (who, despite his protestations, we all know is part of the secretive high command), escalating to withdrawal of Stone Island privileges, or scuffing of the Gazelles, for repeated infractions.
We don't get any of this nonsense in the genteel South. Though I am on my guard as there has been an increase in singing recently and that is how the slippery slope often starts.
Oh and for avoidance of doubt, I consider throwing anything on the field of play to be the act of an absolute dildo and it needs to stop before the fines become something more significant. We aren't exactly in good odour with the men in blazers...
