Not really. If you miss slightly less than two games the cost is the same, and even at today's interest rates you should get more that £2.50 for keeping your money in the bank.
It's not the exact amount that grates, it's the mean-minded penny-pinching aspect of it. 'Here's my £1500'. Oh thanks, that'll be an extra £2.50 for giving it to us. Does anybody know of any other business that behaves the same (apart from Ryanair) ?
