I think there's been wrong on both sides to be honest.
By and large though I think there's a chance for the club to behave more sensitively, rather than leaping on an offense with the harshest punishment.
The loyalty of a long-standing (no pun intended) supporter should count for something here. Seems very petty and feeds beautifully into a tidal wave of negative PR...
It would be easy for a rival fan like myself to use this as an excuse to have a go at Newcastle, but without knowing the history of what has gone on with this ladies ticket, then I will not do so. the above comment is probably how I would want my club to behave over an incident such as this..
