In answer to the previous two posts I had the window open. The player approached the car. I said something along the lines of "do yourself a favour, you're already in big bother. The outpouring of obscenity was repeated, I advised the "if you keep talking I'll keep writing" It was then suggested that I do something potentially life threatening with my pencil and hence the card was once again brandished.
In terms of jurisdiction it is generally considered to be until the "premises" have been vacated. This can be interpreted as as long as in the Car Park.
I am aware of a Referee reporting a Cheshire League Player for misconduct however for a comment made at a Motorway Services on the way home
