Probably the only case credit hunting can almost be justified. If you genuinely attend all games on your own card and you've already booked Qatar then I think most wouldn't want to see someone miss a credit (and possibly future games) due to that. Circumstances that have not really happened before isn't it.
I also think the club should be doing free tickets for this one - or heavily subsidised. (Having said that I think Villa are doing some amazing prices anyway I think I read?).
Perhaps the club should offer no credit for this game, but still require credits to go or something. Nobody missed out then, and maybe a few more get the chance to go.
