Stupid question. Of course it should be one per person. Did season ticket holders get the chance to buy 4? It would be safe to assume that none of the various tickets being sold originate from season ticket holders.
General sale is for anyone who wants to buy a ticket, stubs should've been a priority before general sale, probably before members tbf, but, everyone who was a 'priority' who wanted their ticket, got it.
Also, if I queued up for a general sale, getting it for, say, other mates, I wouldn't be able to get the 4 I need, would I? That to isn't fair.
It's just the way it is pal, you could always go to the ground tomorrow and buy a ticket off someone.
