But you're right, it is clear so why force the issue and make it 'easy' for the stewards, to your own detriment.It's clear that if you don't comply instantly with a steward's request to sit down in North Stand, you are out and banned, particularly if you give any backchat.
Seems very draconian, and I feel immensely sorry for anyone banned as the extreme sanction really does not seem to fit the offense.
