I would guess the average is £16 factoring in kids paying less and non ST holders paying more.
At those prices and no special offers I would guess our attendance would be around 5500.
5500 x £16 = £88,000 (less vat)
At £2.00 even if we sold out every game that would be under £40,000 (less vat)
The food kiosks struggle to service the current numbers so added revenue would be minimal. Add to that the increased policing/stewards we would be much worse off!
