That’s absolutely fine, it’s the people who simply leave their seats empty that are causing the problem.If I return my ticket as an OAP the Club will sell it as an Adult and will not give an OAP or Junior the chance to purchase. Also if you return an Adult ticket, quite rightly you will only get the proportion you paid on your ST. But the Club will then sell that way and above the price. It's not surprising that ST holders who cannot attend the top fixtures chose to sell their tickets by other means.
