Put it this way, There are 2 seats behind me which are available to buy in the East upper. I could take my wife and her brother. But £84 for 2 tickets is just too much. If it was £70- £74 for the pair of them, I would most likely go for it. Its a given already that those seats will NOT be purchased, they have only been bought once this season.
Perhaps the seats do belong to ST holders but they pegged out before the start of the season. The once they were used this season may have been relatives of the deceased who went to see if they would enjoy football. I would hazard a guess that the noise and abusive language in the ES put them off coming again.
