The dilemma for day passers will now be do you watch the Spurs game and not get refunded as they will be able to tell if you streamed it or do you not watch the spurs game and hope you get refunded as you genuinely bought the pass just for the one game.
If you streamed the F1 or earlier events today then I'd say they'd have a right to refuse.
Shame really. It looks like it would have been a good day for a sports day pass.
