Out of our 4-5000 season ticket holders, are there really that many who have tickets they're not eligible for? It's not going to have any real effect on the club either way.
And it's not really worth having a moral crusade about either. If I can get away with paying less than I should for something, even if I'm more than able to pay the full price, then I'm going to do it whether it be football tickets, train fares, prostitutes or whatever. Obviously, that doesn't include any criminal behaviour, but I can live with a bit of mild dishonesty
It doesn't make me, or anyone else who does so, a bad person. That's already covered by plenty of other things.
