When buying a ticket for an event today I took my card out thinking it was fine, and then was told it was invalid. The staff member suggested I'd taken it out too fast, although I must have had reason to think it has gone through. I then did it again, and it went through.
As I suspected, I've been charged twice. The snag is that the extra money will be going to two or more sports clubs, and possibly some other organisations. Is it worth contacting my bank and/or the venue club? I don't fancy my chances given my bank's below par customer service.
