I have a feeling people who have a ticket for the home end won't have a problem.
If you're name is on the ticket and you've got photo ID, you should be laughing!
Can't see them going through with this 'only if you're a ST' carry on. But this is only what I think.
The only advice I'll give you is don't wear colours if you're planning on getting in!
Am I delighted that I've got one for the Celtic end
