All of what you say is absolutely spot on of course... how many times do you hear the phrase "circumstances totally beyond our control"? They'll probably wheel that one out for the re-wiring of the starting tapes, coming up with some excuse about how it's the stadium owners responsibility. If it's effecting your business, you sort it out!
Reading the match report on the Sheffield website, it was just bad luck, so there you go.
