Well well. It appears that Vale fans are indeed bothered about the checkatrade after all!
I don't see an issue with the proposal. If it were an EFL / FA Cup match then yes, i would oppose it but it's a nothing cup that only a small percentage of fans are interested in and therefore it makes sense to cash in. Vale Park is huge and always looks pretty much empty anyway.
In my opinion it's just a handful of fans making a mountain out of a molehill just because it's Stoke City. Is it more about common sense and business sense than about morals?
