Even from a financial perpsective I can't see the value in what Killie has done. Say there were 1,000 paying punters on Wednesday evening. If each attends tomorrows game, that brings in about £2,600 taking into account VAT. There will also be say an additional 400 PATG fans for the rearranged game bringing in say an additional £1,280. That pans out at about £3,900 net.
Now if those with vouchers got in for nothing tomorrow and an additional 400 (probably an underestimate) paid full price that would generate about £5,200 net. The financial difference is about £1,300. Ok so what if a few fans got extra vouchers and every single one was used, Killie would still not lose out or if they did so only by a few pounds - less than one week's wages for one of their better players. In other words, chickfeed to them. By doing what they've done, their reputation has been damaged and they've lost goodwill. Very short sighted.
