How difficult is this to understand? Nobody would be getting punished for not attending. The only fans that would be getting punished would be those that failed to inform the club of their non-attendance and even then they would have to fail to notify the club multiple times during a season before any sanctions were imposed. How that equates to "no sense" is beyond me. I tell you what makes no sense to me - that there are season ticket holders on this very thread that didn't even know City had an in-house ticket exchange facility, and have had since the beginning of last season.
OK, it would be odd for the club to punish people for failing to inform them that they wouldn't be attending when they'd already paid for their ticket.
